Advantages of Using JavaScript for Large Scale Web Application Development


According to some stats, over 85% of websites are currently using JavaScript as a client-side programming language.

JavaScript is one of the most traditional and popular programming languages that allow programmers to build highly interactive, dynamic, and responsive websites and web apps that can work fluently on multiple web browsers, mobile devices, and operating systems, without any complication. Programmers also use it to achieve essential tasks related to the web browsers such as user interaction, browser control, and asynchronous communication.

In fact, with the help of JavaScript Frameworks, you can develop your web projects, especially single page web apps quite quickly and easily. You don’t even need to memorize or write code, just add the libraries from the JS framework and save both your time and efforts.

There are various JavaScript Frameworks out there in the web market such as AnjularJS, ReactJS, NodeJS and a lot more. These frameworks are used to reduce the amount of time and efforts required for developing JS based sites and apps.

JavaScript allows programmers to build large scale web applications like a breeze. Of course, it needs technical skills, but still it simplifies the entire procedure of developing large-scale Web applications.

Let’s get down and explore the advantages of using JavaScript for your next large-scale web app project.

1.  Cross Browser Compatibility: The best thing about JavaScript is that it is supported by multiple web browsers. The list of most popular web browsers includes Chrome, Firefox, Safari, Opera and Internet Explorer.

It allows users to access the web apps on a web browser of their choice, without a difficulty. They also have the option to use all functionality of the site just by enabling the scripting language (if it is disabled).

2.  It comes with tons of libraries and frameworks: JavaScript Frameworks and libraries allow web developers and programmers to reduce the time and effort while building large JS based web applications. There are several dynamic JS framework such as AngularJS. EmberJS, ReactJS and BackboneJS. With the help of these JS frameworks, you can quickly and efficiently develop a highly-interactive and professional looking web app, without any hassle.

JavaScript also offers a wide range of libraries that you can use according to your requirements and specifications. For example, you can generate GUI development using widgets such as Bootstrap, DojoWidgets, jQuery or AngularJS. Similarly, you can make a use of popular template systems including jQuery Mobile, Cascade Framework, etc.

3.  Easy to reduce load on server: The speed of a web app determines its usability. In order to maintain the performance of a web app, the server-side scripting languages need the web server to formulate the user request before sending the response to the user. So, this entire process required extra time despite the user having a super-high internet speed.

But the JavaScript code is prepared on the user’s machine, without even interacting with the web browser. It means all the burden and load on the web server will automatically be reduced when the user gets an instant response.

If you want to boost the overall performance of your large-scale web application, you should use JavaScript. It can reduce the extra load on the web server that helps in providing quick response to the potential users.

4.  Use JavaScript without any specific tool: JavaScript lets you write and edit the code, without using any particular type of program or tool. You can easily open a notepad, and write all your JavaScript code.

In fact, you can also use a several number of editors to find out the mistakes within the JavaScript code. The editor colorize or reformat the script allow users to discover the errors quickly and easily.

5.  Distributes updated response data from the server: JavaScript makes a use of XmlHttpRequest API for retrieving all of your data. The API sends HTTP or HTTPS request to the web server, and then load the response sent by the server in the script. The script works efficiently and updates the current web page based on the responsive data received from the server, without even reloading a brand new web page.

This increases the speed of your site or web app and improves its overall performance by offering upgraded information to the user like a breeze.

6.  Reuse the code again: JavaScript comes with the option to re-use the codes while building a large scale web application. It means you can use the JS code on different pages just by placing the same code in separate files.

Once code has been placed in a separate file, you can save it with .js extension. Thereafter, you can link this file to multiple web pages using the <script> tag to the HTML code of the page.

The option further lets you avoid writing extra code while adding the same functionality to the other sections of the site.

7.  Enables you to extend the functionality: Most of the developers and programmers use JavaScript because it makes it super easy to extend the functionality of the web app. You can make the use of scripting language to craft visual effects on the screen, analyze data, and create more interactive and dynamic web pages, without much effort.

You can also extend the functionality of your site using third-party scripts. However, JavaScript offers a great level of flexibility that can help you multiple functions and features within the web app, without using any specific plugin or tool.


JavaScript is a robust programming language that can help developers and programmers in building large scale web applications easily and quickly.

The advantages mentioned above in this blog post clarifies that JavaScript is not only let you build a high interactive web app, but also helps in strengthening its speed, functionality, usability, and features, without any hassle.
