The fact that 94.5 percent of all websites employ JavaScript indicates its importance as a web technology. JavaScript is a client-side programming language that allows web developers to write bespoke client-side scripts to make web pages more dynamic and interactive. At the same time, developers can use cross-platform runtime engines like Node.js to write server-side code in JavaScript.

The Importance of JavaScript
Most developers use JavaScript as their primary programming language. Each framework offers a unique set of capabilities. The importance of JavaScript in web development is due to these frameworks. As a result, we’re going to show you the top three frameworks that have transformed the way people write with JavaScript and helped it grow in popularity.
Front-end development: If you want to turn a static website into a dynamic one, JavaScript is your best bet. It is the simplest method for creating a dynamic web application with various functions. JavaScript can be used in web projects to connect API endpoints, communicate with the backend, and build dynamic responses such as client-side validations and stunning popup modals.
Backend Development: Using JavaScript and its various frameworks, we can now create a full-stack application. You can edit and manage complete database activities, design an application’s business logic, and create an API from scratch. As a result, the use of JavaScript in web development is growing, as it simplifies the development process.
Game Development: You can create a completely working browser-based game with WebGL. Three.js, a JavaScript toolkit, allows developers to quickly create 3D simulations and games that were previously difficult to create.

Role Of JavaScript in Web Development
Use client-side scripting
JavaScript was created with the intention of being a client-side scripting language. JavaScript is still widely used as a client-side programming language on many websites. Web developers may quickly create bespoke client-side scripts in JavaScript and elegantly incorporate them into HTML. They can also employ JavaScript to make websites interactive, reply to users instantly, and develop richer user interfaces, all while reducing server interaction and load.
Code for the server
Using a cross-platform runtime engine like Node.js, web developers can also create server-side programs in JavaScript. Node.js is a server-side runtime environment that is cross-platform. It also uses the Google V8 JavaScript engine to efficiently execute JavaScript code. Node.js’ built-in libraries make it possible for programmers to run their web applications without the use of external web servers. As a result, web developers may utilize Node.js to write JavaScript code on both the client and server sides.
Simplify the development of complex web applications.
Despite being an interpreted programming language, JavaScript makes sophisticated web application development easier by allowing developers to simplify the application’s composition. To generate shadow DOM boundaries, programmers can use JavaScript libraries. The shadow DOM decouples components of individual JavaScript libraries, in addition to simplifying the web application’s structure. The shadow DOM also allows web browsers to produce documents that contain commonly used HTML tags such as div, select, and input.
