What Are The Uses of Javascript

One of the most widely used programming languages is JavaScript. However, many people, particularly those considering studying JavaScript, frequently wonder, “What are the uses of javascript?” For a long time, JavaScript was mainly used for client-side development. When you see a moving button, text, or any other object on a web page, it’s almost always because of JavaScript. JavaScript has evolved into a very powerful programming language that is no longer limited to the web. After reading this article, you will understand what are the uses of javascript.

What is Javascript?

JavaScript is a scripting language for creating and controlling dynamic website content, which is defined as anything that moves, refreshes, or otherwise changes on the screen without requiring a manual reload. JavaScript is used to develop the majority of the features and apps that make the Internet so important in modern life. Consider some of the web services you use on a daily basis, such as when your Facebook timeline instantly changes on your screen or Google offers search results based on a few letters you have typed. That’s JavaScript in action in both circumstances.

History of JavaScript

The first versions of JavaScript were created for the Netscape Navigator Web browser in the late 1990s. Brandan Eich, a Netscape programmer, created a new programming language in September 1995. It was initially known as Mocha, but it was renamed to LiveScript and then JavaScript. Web pages were static at the time, with minimal user interaction other than clicking links and loading new pages. JavaScript enabled adaptive content, animation, and form validation on the page for the first time. For a long time, JavaScript was only supported by a small number of browsers. The most popular browser, Microsoft Internet Explorer, did not support JavaScript until much later. 

Rather, Microsoft developed JScript, a proprietary client-side script. Programmers who wanted to create dynamic web pages in the early days of the Web were frequently forced to choose between two browser families. This wasn’t ideal because it made the Internet less accessible to everyone. JavaScript was not extensively accepted and standardized until 1999. Browser compatibility remained a problem for almost a decade following standardization.

What Are The Uses of JavaScript?

Here is the detailed answer of the question: what are the uses of JavaScript?

Web Applications

JavaScript is also often used to create web apps that do not use web contexts. JavaScript interacts directly with browsers rather than sending signals through servers, allowing developers to develop fast web applications. It makes use of Application Programming Interfaces (APIs) to increase features and improve speed. Applications can avoid parsing and storing extraneous information by just requesting the required data, allowing them to use resources more efficiently.

Web Servers

Node.js can be used to develop a web server. Node.js is event-driven, which means it doesn’t wait for the preceding call’s response. The Node.js based servers are fast, don’t need buffering, and transport data in chunks. The createServer() method of the HTTP module can be used to create the server. When someone tries to access port 8080, this procedure is called. The HTTP server should respond with HTML, which should be supplied in the HTTP header.

Web Development

JavaScript is a scripting language that is often used to create web pages. It enables us to add dynamic behavior to the web page as well as special effects. It is pimarily used on websites for validation purposes. JavaScript allows us to do complicated tasks and allows websites to communicate with users. It is also feasible to load the content of a document without page reload using JavaScript.


Games like Angry Birds, Bejewelled, and Polycraft are built using JavaScript. When used with HTML5, JavaScript can develop powerful games that can be played with just a keyboard. The combination allows for the creation of fully-fledged, interactive games using various engines, libraries, and versions of common web languages. The Ease JS package offers easy ways for working with rich graphics to create generative art, games, and other highly graphical experiences. The library also includes 2D picture sprites, which combine multiple images into one, speeding up gaming by decreasing server queries and saving bandwidth. 

Mobile Applications

Mobile devices are widely utilized to access the internet in the current scenario. Anyone can also create an application for non-web environments using JavaScript. JavaScript’s features make it a powerful tool for developing mobile apps. The React Native framework is a popular JavaScript framework for developing mobile apps. We can create mobile applications for a variety of operating systems using React Native. We don’t need to write separate codes for the iOS and Android platforms. It only needs to be written once and run on multiple platforms.   

Smartwatch Apps

Pebble, a famous smartwatch manufacturer, has launched Pebble.js, a simple JavaScript framework that allows developers to construct JavaScript applications for Pebble watches.

Flying Quadcopter

That’s right, you read that correctly. Node.js is installed on many commercially available quadcopters, some of which come with a simple operating system. This means you can use JavaScript to program a flying quadcopter. JavaScript is the most user-friendly programming language on the globe, with a wide range of capabilities. It’s encouraging to see that it’s generating such a diverse set of applications.

Server Applications

A server-side component is present in a vast number of web applications. To generate content and process HTTP requests, JavaScript is employed. Node.js allows JavaScript to execute on servers. Node.js provides a server-side environment with all of the tools required for JavaScript to run. 


In this blog, you got the complete details about what are the uses of JavaScript. Moreover, the information about what is javascript and the history of javascript is also provided. JavaScript can be utilized in several different ways. It can bring interactivity to web pages as a client scripting language. It’s ideal for creating web apps because it communicates directly with browsers. Moreover, it can build excellent web servers when combined with the Node JS framework, and its other frameworks can be utilized to make mobile apps. Developers may utilize JavaScript with HTML5 to make games, while the Reveal JS and Bespoke JS frameworks let them create slideshows and presentations. Hopefully, now you understand the usage of Javascript, and you can answer anyone who asks what are the uses of javascript in the future. Moreover, if you are facing any difficulties, then you can take Javascript assignment help anytime.
