How Good Is JavaScript coding for Building a Large Scale Web Application?

According to the most recent statistics posted on w3techs.com, more than 89% of websites currently use JavaScript as a client-side programming language. As a cross-platform and lightweight programming language, JavaScript coding makes it easier for programmers to build responsive websites and web applications that work with seamlessly with popular web browsers, operating systems and devices. It is also widely used by programmers as part of the web browsers to accomplish important tasks like browser control, user interaction, and asynchronous communication.
Also, the programmers have option to use JavaScript as a server-side scripting language through Node.js and similar runtime environment. At the same time, they also can use a variety of open source frameworks to reduce the amount of time and effort required for building JavaScript applications. It can also be used along with HTML5 and CSS for creating web applications and games. So you can always consider using JavaScript as a dynamic client-side programming language for building large scale web applications.



Advantages of Using JavaScript for Large Scale Web Application Development
Supported by Major Web Browsers
JavaScript is supported by most of the widely used web browsers including Firefox, Chrome, Internet Explorer, Safari and Opera. It is also supported by the new web browsers whose vendors have implemented JavaScript. So the users can access the web applications using JavaScript regardless of their choice of web browser. They also have option to access all functionality of the website by enabling the scripting language if it is disable due to some reason.
No Need to Use Any Specific Tools
JavaScript is an interpreted programming language. So you can easily write the code without using any specific tool or program. You can simply open a notepad, and start writing JavaScript code. Also, you have option to use a number of editors to identify the mistakes in the code. The editors colorize or reformat the script to make it easier for users to identify the errors.
Option to Reuse the Code
You can further reuse the JavaScript code across multiple pages simply by placing the code in separate files. After placing the code in a separate file, you have to save the file with.js extension. The file can be linked to multiple web pages by using the <script> tag to the HTML code of the page. The option enables you to avoid writing additional code while adding the same functionality to various parts of the website.
Many Libraries and Frameworks
You have option to reduce the time and effort required for building large JavaScript applications by using several frameworks and libraries. Many programmers prefer using dynamic JavaScript frameworks like AngularJS, Backbone, Ember and React. However, you still have option to choose from a long list of JavaScript libraries according to your specific needs. For instance, you can effectuate GUI development using widgets like DHTMLX, Bootstrap, jQuery UI, DojoWidgets or AngularJS. Likewise, you use popular template systems like jQuery Mobile, Handlebars, Mustache and Cascade Framework.
Comparatively Faster
As noted earlier, JavaScript is a client-side scripting language. So the code is executed on user's system. As the code is executed without any server interaction, the processing is done at a comparatively faster. The faster processing enables the web application to keep the users engaged by delivering richer browsing experience.
Deliver Updated Response Data from the Server

JavaScript further uses the Xml Http Request API for data retrieval. The API sends HTTP or HTTPS requests to the web server, and load the response sent by the server in the script. The script can easily update the current web page based on the response data received from the server without reloading a new web page. So you can boost the web application's performance by providing updated information to the users without reloading the web page completely.
