INTRODUCTION:

High-level programming languages like JavaScript are largely used to build dynamic and interactive web sites. Brendan Eich developed it in 1995, and since then it has grown to be of the most widely used programming languages in the world, with millions of developers using it to construct everything from mobile apps to online applications.

JavaScript’s capability to alter web page content in real-time is one of its primary characteristics. A web page’s content can be changed dynamically based on user input or other factors using JavaScript, which allows developers to create animations, respond to user actions, and more.

NECESSARY OF JAVASCRIPT:

In addition to HTML and CSS, JavaScript is frequently utilised in front-end web development to produce responsive and interactive user interfaces. As a result, programmers can construct dynamic and interesting web applications that work flawlessly across a range of gadgets, including desktop PCs, smartphones, and tablets.

JavaScript is widely utilised not only in front-end web development but also in back-end web development, where it drives server-side applications and APIs. Developers may easily design complicated web apps by using JavaScript to build scalable and high-performance back-end systems with the aid of frameworks like Node.js.

JavaScript’s popularity can be attributed in part to its usability and adaptability. Any current web browser may run JavaScript code without requiring a plugin.

CONCLUSION:

A high-level programming language primarily used for front-end and back-end web development, JavaScript is described as such. It is one of the most widely used programming languages in the world thanks to its adaptability, simplicity, and real-time manipulation capabilities. JavaScript is anticipated to continue to be a vital tool for programmers creating interactive and dynamic web applications as the web continues to develop.
