Posted on by tbsupadminnxtbackendacc

To be able to answer the questions about Jmeter Interview Questions you must go through the most frequently asked interview questions about the tool. Let’s have a look.
Q 1: What is JMeter?
Ans: JMeter is a Java-based tool used for Performance and Load Testing. It simulates virtual users and sends multiple requests to the server. It then collects the response and other details to assess the performance of the system under different conditions.
Q 2: Explain Samplers and Thread Groups in JMeter?
Ans: Sampler generates sample results sets with different attributes like time, data size, etc. These allow JMeter to send requests to the server. Some of the most frequently used samplers are HTTP requests, JDBC requests, etc.
Thread Groups are user sets that contain the details of the number of users to be loaded into the system and the time gap between them. It is the basic step for any load testing activity.
Q 3: What is a pre-processor element? Name some.
Ans: A pre-processor is something that is executed before the sampler executes. It can be used to set the values for the sample request.
Some of the pre-processor elements are:

  • HTTP URL re-writing modifier
  • BeanShellPreProcessor
  • HTML link parser

Q 4: What is the order in which the test elements are executed?
Ans: The sequence is:

  • Configuration elements
  • Pre-processors
  • Timers
  • Samplers
  • Post-processors
  • Assertions
  • Listeners

Q 5: What is a regular expression? What is the difference between “contain” and “matches” in the regular expression?
Ans: A regular expression is a pattern used to search and match a particular text.
In a regular expression, “contain” means the search text can be some part of the matched expression. Like “press” in “expression”. “Matches” on the other hand need to match the complete expression. “exp.n” for “expression”.
Q 6: What are the configuration elements?
Ans: A configuration element works in parallel with Samplers. They are used to set the default values for variables.
Q 7: What is a timer in JMeter? Mention different types of timers?
Ans: JMeter is designed to send requests to the server continuously without a break. If we need a pause in between successive requests we can make use of the timer. There are many timers available and some of the most common ones are:

  • Constant Timer
  • Gaussian Random Timer
  • Uniform Random Timer
  • Synchronizing Timer

Q 8: What is an assertion? Name some assertions in JMeter.
Ans: Assertions are used to help validate and verify the server response with the expected results.
Some of the common Assertions are:

  • Response Assertion
  • Duration Assertion
  • Size Assertion
  • XML Assertion
  • HTML Assertion

Q 9: Can you do spike testing using JMeter?
Ans: With help of a synchronization timer we can achieve a spike effect in JMeter. A synchronizing timer will block all requests till a particular number of threads are blocked and then release them all together, creating a huge load or spike.

  • Aggregate Report
  • Summary Report
  • View Results Tree
  • Spline Visualiser

Q 17: Name the different types of controllers?
Ans: There are mainly 2 types of controllers in JMeter:

  • Samplers Controllers – They are used to send specific requests to the server and simulate the user request.
  • Logical Controllers – Logical Controllers control the flow or order of processing of the Samplers. It can be used to change the sequence of requests coming from the child element.

Q 18: What is a workbench?
Ans: Workbench is like a storage area for components that can be added to the test plan as per the need. They are not saved with the test plan but get saved as Test Fragments separately.
Q 19: What is co-relation in JMeter?
Ans: Co-relation is the process of extracting a value from the response received, to use in upcoming requests. This is especially useful for session-id, cookies, etc.
Q 20: Can JMeter be used for load testing mobile applications?
Ans: Yes, JMeter can be used for sending HTTP or HTTPS to the server from your mobile application provided both the mobile and the server are on the same network.
Q 21: What is a root CA certificate?
Ans: In the case of HTTPS requests, when the browser hits the server, authentication is required. JMeter can generate this certificate temporarily to intercept the traffic and record the actions. To perform the action on mobiles, the certificate needs to be installed on your mobile as well. These are called the root CA certificates.
Q 22: What is the default screen in JMeter?
Ans: The default screen in JMeter opens the Test Plan and Workbench tabs.
Q 23: What is a Test Plan and what the important elements in the Test Plan?

  • Use parameterization where ever possible
  • Avoid the functional mode
  • For the output select CSV instead of XML
  • Disable unwanted graphs, they consume a lot of space

Q 25: What is Beanshell scripting?
Ans: BeanShell is a lightweight java scripting that can help you with complex and application-specific tasks.
Q 26: What is the difference between Gaussian and Poisson Timers?
Ans: Both the timers use mathematical formulas to create delays and offsets. The difference between the two is that in the Gaussian Timer the deviation value is calculated whereas in Poisson the lambda value is calculated.
Q 27: How can you configure the master-slave configuration?
Ans: The master-slave configuration is used for distributed load testing.
To configure we can:

  • Edit the JMeter.properties file on the master machine and add the IP addresses of the slave machines in the remote_host field.

Q 34: What is the latest version of JMeter?
Ans: The latest version is JMeter 5.4.1 and it was released in January 2021.
Q 35:What is Throughput in JMeter?
Ans: Throughput is the number of requests served or successfully processed per unit of time.
Throughput = (No. of requests)/(total time)
Q 36:How can you calculate the number of concurrent users?
Ans: Concurrent users mean the number of users performing the same operation at the same time in the system. The number of users in the system can be found out using the number of threads. But a vague calculation of the number of concurrent users – if there are
100 unique visitors, with each visitor spending 10 mins in the system. Then we can say that the number of concurrent users is 100/10 = 10 users.
Q 37: What is the load time in JMeter?
Ans: In JMeter, load time refers to the total time before sending a request to after receiving a response. For multiple threads, the load time is calculated at the thread level and is the total time between the thread request and the response received.
Load Time = Time after a response is received – Time before a request is sent.
Q 38: What are Monitor Tests?
Ans: Monitor Tests are generally used for stress testing. They provide additional information about server performance. It also helps to monitor multiple servers from the console.
Q 39:Can we use Selenium scripts in JMeter?
Ans: Yes we can. One way is by using Junit libraries to create Selenium scripts, save them as Jars and copy them to the JMeter directory. Another way is to add the web driver sampler plugin to the JMeter ext folder.
Q 40: Explain how JMeter works?
Ans: JMeter simulates multiple concurrent users using threads and sends requests to the server, create a load. It then measures the time and performance of the server and displays it in the form of tables and graphs.
Q 41: What is the ramp-up period in JMeter?
Ans: While running load tests, all the users are not loaded into the system together. The number of users is slowly and progressively increased to better understand the system bottlenecks and performance. The ramp-up period is thus the time taken for all the users to get into the system.
Q 42: What is the Rendezvous Point?
Ans: The Rendezvous Point is the term used with stress testing. It is the point at which all the delayed requests are released to hit the server and create a spike.
Q 43: What are Post-Processors?
Ans: Post-Processors are the elements of the test plan that are executed after the sampler request execution. Generally, they are used for extracting some values from the sampler response.
Q 44: What is the 90% line in JMeter?
Ans: 90% line is one of the metrics of the Aggregate Report Listener. It means 90% of the responses were within this limit. It is similar to the percentile value and can also be called the 90th percentile of the response time.

Q 45: What are the common techniques of Performance Testing?
Ans: The most common performance testing techniques are:

  • Spike Testing
  • Load Testing
  • Volume Testing
  • Endurance Testing
  • Stress Testing

Q 46: How can you run JMeter in GUI mode?
Ans: The following command is used to run JMeter in GUI mode:
:jmeter -n -ttest.jmx -l test.jtl
Q 47: How can you analyze the JMeter results?
Ans: The JMeter results are stored in the .jtl file. It is possible to add different graphs like the response time graph, aggregate report, etc. We can also analyze the response time and the TPS (transactions per second). In some cases, we may also want to add some plugins to get additional graphs.
Q 48:Is it possible to configure email notifications in JMeter?
Ans: Yes, we can use the SMTP sampler to trigger emails at the start and end of the JMeter tests.
Q 49: What are the different types of recording in JMeter?
Ans: JMeter allows manual and automation recording. For automation recording, we can use the workbench to record the script. For manual recording, we can make use of fiddler or network log (F12)
Q 50: How can you forcefully stop a test in the middle of the execution?
Ans: For Windows machines, we can double-click on the stoptest.bat and shutdown.bat to forcefully stop the test. In the case of Mac, stoptest.sh and shutdown.sh files need to be double-clicked.

Software Testing Tutorial For Beginners

Posted on by tbsupadminnxtbackendacc

We are sure you are here because you want to know what software testing tutorial is all about and how will it take you to the next level of your career. Before we start, software testing methodologies of verifying and validating that all the bugs/faults in a software product are resolved and is fit for use by the end user.

Software testing doesn’t just stop at fixing all the bugs, but building a strategy that can improve the products usability, accuracy and reliability. In this blog, we’ll help you understand the concepts and techniques involved in the process which will certainly help you to decide if this is the right profession you are looking for.
software testing tutorial
Software testing can be divided into two paces:

  1. Validation
  2. Verification

Validation is referring to various types of pre-specified tasks to ensure it matches with the customers’ requirements. It involves tasks like automated testing, running scripts and checking functional dependencies.
Whereas, Verification refers to checking the tasks that make the product actually run in its real-time. It involves reviewing the test cases, inspections, and documentation

Some key differences are as follows:

S. No               Validation           Verification
1 Does the final product actually meet what was proposed? Is the product built with respect to the requirements?
2 Automated & Manual Testing Document reviews, inspections and walk-throughs
3 Execution of application required Does not require execution of software

Types of Software Testing
If you ever had to visit a training institute or an interview, you certainly must have heard the terms automation and manual testing. Well, that’s nothing but types of testing. So let us classify these two:
Manual Testing:

Manual testing is the process undertaken by a tester himself to check if the systems perform as expected. In other words, the testing is done without using any automated tool or script.
The Manual Tests include a set of test cases defined by the tester and then each case is verified for their respective functions. To do this, the tester has to follow some steps:

  • Requirement Analysis

To successfully run manual tests, you should first know what the application is all about and what output is expected from its behaviors. For this, you need to analyze its requirements and study it thoroughly. By doing this you will know what you are testing and makes reaching your goal a lot easier.

  • Writing Test Cases:

A well-written test case allows you to understand and run the tests with ease. It is like a guide that supports you during your testing process. There are many software’s now that allows you to tip down those cases. While you write the tests, make sure you think like an end-user. After-all you are testing it for them.

  • Regulate the Test Cases

Once you are done writing all test cases, it’s time for executing each one of them. Jot down the “Passed”, “Failed” and “Skipped” tests and leave the rest for the developers to fix.

  • Logging of Bugs

Once you identify the state of the bugs, make sure you follow a proper medium to communicate them to the developing team. A lot of developers prefer using the Mozilla Bugzilla, which is an add-on to the browser.

  • Reporting

The final steps expect you to report any additional assumptions and conditions which couldn’t be marked. Also mention suggestions to improve validations and processes.
Automation Testing


Automation testing, as the named suggests, is automated. It differs from manual testing in a way that uses automated scripts for running the test cases. It is a boon in today’s testing market.
Automated tests are basically conducted on large projects, which otherwise would consume a lot of time in manual. Some companies also run automation after the manual to make sure all the test cases are covered. Follow the below steps before proceeding with your automation tests.

  1. Learn and decide what tests to automate
  2. Test as often as you can
  3. Selecting the right tool for automation
  4. Make sure each test has its own contribution towards the efforts.
  5. Have quality data in hand
  6. Create automated scripts that can accommodate changes in the UI

When should you opt for automation testing
Always go for test automation if:

  1. The project is large and complex
  2. The project requires continues testing for the same area
  3. Time constraints
  4. The software is stable with respect to manual tests.

Tools for automation tests:

The Techniques of Software Testing
Believing you now have a clear idea of what software testing and its types are, let’s see the techniques used. There are 2 techniques defined in software testing:
1. Black-Box Testing
Black Box Testing deals with the internal working of the system where only the system coder has access to the source code. Hence, while testing, the tester has to perform the tests under the guidance of the developing team for inputs and outputs.
Black box testing clearly separates the tester’s and developer’s point of view to look at the software.  Hence is well-suited for large code segments of the project. But certainly, this complicates the designing of test cases.
2. White-Box Testing
White Box testing deals with the program logic and structure of working. For this, you need to first understand the internal working of the code, which is easier than working with the code.
Since the user has an understanding of how the code functions, it’s easier to identify the data to be tested. That’s why it’s also called as glass-box testing or open-box testing.
Levels Of Testing
During testing, you come across various levels of steps. In this section let’s have a brief look at these.
The Levels are divided into 2

  • Functional Testing
  • Non-Functional Testing

Functional Testing
Functional testing is performed when the actual software development is taking place ensuring that all its requirements are met. Not to forget, the test is performed only when a piece of the module is complete.
The process involves 5 steps:

  1. Defining the functionality to be checked
  2. Creating the test cases
  • Comparing the output based on the test cases
  1. Execution of test cases and writing scenarios
  2. Comparing the actual and expected results

Functional testing can be performed by the following tests:
1) Unit Testing: The tests are conducted before the program is handed to the testing team for executing test cases
2)Integration Testing: This testing is done by putting together parts of the application to determine if they together functional properly.
3) System Testing: This testing tests the whole system as one. Once all the system components are integrated, it is checked for the working on specified quality standards.
4) Regression Testing: Many times, when there is an unplanned bug in the system testing, there are possibilities that it might have affected or will affect other components in the system. In such a case, regression testing is carried out.
5) Acceptance testing: Considered as one of the important tests in the functional testing phase, acceptance testing is done purely by the Quality Assurance team. They check it for the final specification meeting the requirements.
6) Alpha Testing: A test conducted by the QA team and the developers, which combines all of the above tests for a final review before it’s tested by the end-users.
7) Beta Testing: The final test before its release, the beta test is done by a chosen audience. The audience may be any non-technical team or a group of new users. The application is run in real-time to check the application runs as expected.
Non-functional Testing
Non-functional testing deals with bugs that are caused by any external factors like network, database processing, client-side downtime, etc. The non-functional testing types include:
1) Performance Testing
Identifies any performance issues that affect the speed, stability, and reliability of the application. Performance testing can be further divided into Load testing and Stress testing based on its qualitative and quantitative aspects.
2) Security Testing
As the name implies, security testing checks for flaws related to the security of the program. It includes confidentiality, validations for inputs, attacks due to SQL insertions, scripting and virus attacks, etc.
Conclusion

So the reason is much simpler now, you know what you deserve in a tester’s career. So if you are a beginner, make sure you understand all the aspects of testing well before jumping in. We will be happy if you are even halfway through to deciding your career in testing. Take your first step towards being an excellent tester.

It is important to get the resume made with accuracy and precision to get the most awaited call from your HR.

In order to achieve it, one must have a unique resume that makes HR call for them immediately.

It is your opportunity to get the most done within a limited time frame. With so much of task in hand, the recruiters don’t usually check out every single detail in a resume.

They will just have a brief scan of the whole resume and will decide your future with them.

In order to get this done with results, one must have an organized, appealing and error-free resume.

Make a Good Impression

With a limited time frame, one must have the ability to capture their essence in a single or maximum two sheet.

This will allow one to easily process with the whole professional qualification with a tint of personal life.

In order to give this snapshot, one must take the helpof pointers that allows an easy explanation in one work without description.

Especially, if the soft tester is a fresher then it becomes more important to make the resume attractive with no prior experience with work.

Start with the Basic

Instead of simply writing the resume, one can start with basics or consider is pre-activities.

  • Make a proper list that must contain all the information about work experience, education, skills, projects, technologies, a platform to work on, certifications, diplomas, etc.
  • You don’t have to work on the format in the template and initial stage. Simply use a notepad or sticky notes to get every single detail together. It will compile all the details about you on a single page.
  • Make a list as the Technical skills containing –JIRA, Manual Testing concepts, BN Scripting beginners, etc. Then move towards education point that will contain 10th, 12th, graduation, post-graduation, etc. details. Similarly, add on the company experience (if any) in one part from the starting of the career till now. It must contain year, company name, designations, key responsibilities, project details, etc.
  • Then, pick a list one by one, say technical skill then sort them up as per the proficiency in that skill. You can say that the rating of every single skill will be done out of 5, the thing you are best at will have 5 marks whereas the familiarity prospect only has 1.
  • Go through the whole list once you are done, every single part and make sure that you have not missed out some important part. If yes, then add them or make a new column as certifications that can add your certificates details.
  • Then try to see your weakness, just because you are trying for the tester’s job doesn’t mean that you will have it with the blink of an eye. It is essential to know where you are lacking and the area that you need to work on.

Once, the details are compiled together then comes the template part to give it the proper flow.

  • Certifications – It must contain all the certification that you are involved in. However, you don’t have to fake anything since companies can ask for the proof. Hence, it is better,to be honest with the section.
  • Technical Skills –This section must contain the information about the technical skills that are acquired by the employee. It can while doing the job or some other skill that one might have.
Writing the Project Format

It can be in terms of education or certification or maybe the professional background. You can mention the extra details in the second sheet.

Things to keep in Mind

  • Brief and simple resume has more value thanstack up and colourfulresume.
  • The objective must be clear and not confusing since it will be the first thing an employer notice.
  • Relevant skills must be highlighted or you can bold them to make sure that employers have a look at them.
  • No need to add unnecessary information such as Father’s detail, age, weight, etc.
  • Resume and Curriculum Vitae at the top of the resume are long gone trend.

29 Best Software Testing YouTube Channels to follow in 2024

Posted on by tbsupadminnxtbackendacc

Hands-down videos are the best way to learn. if you are someone who is in search of software testing youtube channels these channels can be of great help in teaching you about  software testing/quality assurance

Stating the dilemma at first

All the Youtube channels that we have listed here are doing a great job. No doubt in that.  Their videos are highly informative and would be of great help for aspiring as well testers who are in the quest to learn something new. However, there is a problem!

The emphasis on automation is overwhelming. Software testing has to offer much more value than automating tests. Automation is merely a productivity-increasing technology rather than a QA process.
Recently there was an interesting post on Linkedin by Simon Prior on Linkedin. which clearly described the overall situation through a diagram.

Automation is just a part of testing
image stylized than original for representation purpose

The issue reminds me of the famous quote by Jim Hazen it’s automation, not automatic.
in short, Automation can save a lot of time so that testers can focus on other forms of testing. For instance, functional regression test cases can be too much in number and there is a dire need for automation.
Coming back to the picture, YouTubers need to focus on other aspects of testing such as manual testing, security testing, user testing, etc.

Their impact on the testing scene is beyond comprehension and they can change the situation that persists now by evoking interest in aspiring testers as there is a dire demand for other testing-related skills  at present.

Can we learn software testing through youtube?

Yes, it is very possible to learn software testing via YouTube.

Top 20 Programming Languages For Mobile App Development

Posted on by tbsupadminnxtbackendacc

Mobile App has to be stable, secure and easy to use to survive the competition. To make sure that all the mentioned factors are perfect, you need a robust programming language for development. Which are the currently used programming languages for mobile app development?
Have a look.
1. JAVA
JAVA
In the last 2 decades, Java has been one of the strongest programming languages in the world. Java initially started as a project in Sun Microsystems called GreenTalk.
During the initial days, Sun Microsystems wanted to have some applications developed for embedded systems such as microwave ovens, washing machines, coffee machines and so on.
Initial Idea was to use C++.
In 1995, James Gosling suggested the name to change to Java and in the same year, Java 1.0 Alpha was released for download. Java SE 5 was released in 2004 and is the 2nd largest benchmark on Java versions.
This brought some new and useful features like annotations, a loop to iterate over collections, etc.
It is largely favored by app developers in companies because it is flexible and easy to use which minimizes the scope of error during development.
Java is backed by a community that makes fixing technical glitches very easy and efficient.
2. PYTHON

Guido van Russom created Python language in 1980.
Over the course of time, it has evolved and become such a huge application development language.
A large majority of individual users and business enterprises have started using Python in recent years mainly because it is developer friendly, easy to learn and use.
Debugging is very easy in Python because each line of code is interpreted one by one which makes it the choice of app development language of beginners.
It can be easily integrated with Java, C++, and C and has a large set of functionalities that come pretty handy for quick application development.
It is a portable language which means that it can be run on a variety of operating systems like Windows, Linux, Mac OS, etc.
And the best part is that it is open source and freely available.
3. PHP

In 1995, Zend Technologies came up with a server-side scripting language called PHP.
It is used for all purposes including application development but initially, the main objective for developing this language was to create websites.
Those who know PHP are capable of building dynamic websites, various kinds of mobile apps, and web applications as well.
Recently, PHP 7 was launched and it showed drastic improvement over its previous versions.

Especially the speed. Some other improvements are as follows; type declarations, error handling, new operators, easy user-land Cryptographically Secure PseudoRandom number generator (CSPRNG).
Unicode support for emoji and international characters has also been introduced in PHP PHP is most commonly used in creating GUIs, content management systems, code project management tools, Facebook apps, etc.
4. BUILDFIRE
BUILDFIRE
Buildfire.js helps you create robust applications using Build fire SDK and JavaScript.
Buildfire is commonly used by a lot of businesses which eliminates the need for the developer to create an application from scratch.
The developer only needs to create a specific process for the business. This results in rapid application development.
The Buildfire marketplace has a bunch of plugins that you can add to Buildfire.
5. C++
C++
It began as an expanded version of C and was created by Bjarne Stroustrup in 1979 at Bell Laboratories in Murray Hill, New Jersey.
People came to the realization in 1983 that C++ offers much more than C. It is a mid-level programming language which means that you can use C++ to develop high-level applications and also the low-level libraries which work very close to the hardware.
It is object-oriented which means that it uses concepts like inheritance, polymorphism, encapsulation, and abstraction and so on.
C++ allows the creation of a function inside a function which is why it is called a block-structured programming language.
The speed of execution in C++ is very high which makes it the choice of application development language of many developers.
It is used in operating systems, device drivers, web servers, cloud-based applications, search engines, etc.
Also, it can be used to create some other programming languages meaning there is a high possibility of an existing programming language being derived from C++.
6. JAVASCRIPT
programming languages for mobile app development
It is the hardest language to master but the easiest to begin with. JavaScript is a really old programming language and some of its features have become useless.
JS is the short form of JavaScript and is a largely used technology in the World Wide Web alongside CSS and HTML.
Interactive web pages can be created using JavaScript and a large majority of websites use it.
Popular web browsers use JavaScript engine for its execution. It was developed 23 years ago by Brendan Eich at Netscape Communications. Syntax, standard libraries, etc. in Java and JavaScript are the same but there are tons of differences as well.
7. C#
c#
Also known as C sharp, it as object-oriented which means that it uses concepts like inheritance, polymorphism, encapsulation, and abstraction and so on just like C++.
This programming language can be used for all languages and is developed by Microsoft. Games, mobile applications, web services, server applications, etc. can be created easily using C#. Anders Heijlsberg is created C# in the year 2000.
The stable release 7.3 was launched in May 2018. C# applications are low on memory and power consumption and can compete directly with C or C++.

8. HTML5
programming languages for mobile app development
HTML5 is greatly useful in web-based mobile application development.
The latest version of HTML5 features multimedia support, multi-platform functionality for different gadgets and programs, and quick market deployment.
Android and IOS application developers find HTML5 particularly useful because of its flexibility and rapid application development capability.
9. RUBY
ruby
Ruby is most commonly used by designers for web development and serves as the base for Ruby on Rails.
It is somewhat similar to PHP.
Ruby is indeed the friendliest programming language when it comes to Android and IOS application development.
It is backed by a community that will help you in case you face any issues. Bloomberg, Airbnb, Twitter, etc. use Ruby on Rails to power their online platforms.
10. KOTLIN

Kotlin is a fairly new programming language as compared to those mentioned above.
It first appeared in 2011 and is designed by JetBrains and open-source contributors.
Stable release 1.3.31 was released just a few days ago in April 2019.
Its main features are; conciseness, compactness, compatibility with JAVA, and easily understandable.
Its main focus is mobile application development for which it uses a simple syntax.
11. SWIFT
programming languages for mobile app development
Swift was developed by Chris Lattner and Apple in 2014.
This programming language is mostly used in the development of IOS applications since it is developed by Apple. It is capable of executing both Cocoa Touch and Cocoa platforms.
Swift takes inspiration from several other programming languages such as Haskell, Python, C#, Ruby, and CLU and so on.
It is a very simple language and requires fewer lines of coding to develop an application.
The applications produced using Swift are scalable because they have the capability to sustain new features.
The memory consumption of Swift applications is on the lower side which has a direct positive impact on speed and performance.
However, Swift is a fairly new language and programmers are skeptical about its functionality and stability.
12. OBJECTIVE-C
programming languages for mobile app development
Application development through Objective-C takes a long time because the programmer has to write long lines of code.
However, learning this language is fairly easy because a large majority of features are taken from C language.
This programming language is mostly used by Apple for the development of IOS and Mac OS apps. Brad Cox and Tom Love developed this language in 1985.
Since it is an old language, it is a bit mature and has improved a lot.
13. J-QUERY
jquery
It has a learning curve attached to it. J-QUERY was developed in 2007 by The JQuery Team and aimed to facilitate client-side HTML scripting.
Sizzle is the selector engine of J-Query and does a pretty good job at traversal and manipulation.
The creation of a new programming style becomes a possibility courtesy of Sizzle.
It eliminated most of the JavaScript drawbacks. J-Query simplified the operations which took more than a while on JavaScript.
It is preferred by programmers because it has effect libraries and a personalized UI.
14. SQL
programming languages for mobile app development
It is one of the oldest programming languages. SQL (structured query language) was developed in 1974 by Donald D. Chamberlin and Raymond F. Boyce.
Relational algebra and tuple relational calculus form the foundation of SQL.
It is particularly useful in retrieving data for a database in a quick and reliable manner.
Data access control, data manipulation, data definition, and data query is possible in SQL.
The standard of SQL database is pretty high (ANSI and ISO standards) which eliminates the need for heavy coding.
15. BOO
programming languages for mobile app development
Developed in 2003 by Rodrigo B. De Oliveira, Boo is a free programming language.
It is considered an all-rounder and is pretty useful in general for application development.
It works well with Mono frameworks as well as with Microsoft.NET.
Since it is a new language, programmers don’t use it quite often and neither it is as powerful as some of the older programming languages like Java, Python, and C++.
However, its unique features include First class functions, list comprehension, and closures.
16. SCRATCH
programming languages for mobile app development
Scratch was developed by MIT Media Lab Lifelong Kindergarten Group in 2002 to allow programmers to culminate in games, animations, and storytelling.
This programming language was targeted at students but users of all ages can learn and use it easily.
17. QML
programming languages for mobile app development
Qt Modeling language, QML for short is a good programming language for creating mobile applications.
QML was developed in 2009 by QT Project and is somewhat similar to JSON and CSS. QML is less preferred by programmers because an app developed with QML will not work without Qt quick compiler which is only available with the commercial QML version.
18. SCHEME
programming languages for mobile app development
This programming language comes with imperative and functional programming capabilities.
The learning curve attached to this programming language is easy and short as compared to other programming languages.
It was developed by Guy L. Steele and Gerald Jay Sussman in 1970.
19. RUST
programming languages for mobile app development
It is sponsored by Mozilla and is similar to C++.
This programming language comes with imperative and functional programming capabilities.
Some advantages of Rust are; ability to identify errors during compilation and inbuilt concurrency support.
Rust is a young programming language developed by Graydon in 2010.
Some disadvantages of Rust are; complicated installation process, difficult to understand and apply advanced functions, and irrelevant tools.
20. ACTION SCRIPT
programming languages for mobile app development
Gary Grossman developed Action Script in 1998 for creating websites and software.
It can also be used to develop mobile applications. Version 1 and 2 of Action Script can run on the same hardware.

These were the top 20 programming languages for application development. Hope you find it useful.
