What is JavaScript?

The programming language known as JavaScript is frequently used to create dynamic and interactive elements for websites. Additionally, it is utilized in the development of web-based software and applications, desktop and mobile applications, and server-side programming. It is a client-side prearranging language, implying that the code is executed by the client's internet browser instead of on the server. When creating and styling websites, JavaScript is frequently used in conjunction with HTML and CSS.

JavaScript is a lightweight programming language that web developers commonly use to create more dynamic interactions when developing web pages, applications, servers, and or even games.Developers generally use JavaScript alongside HTML and CSS The scripting language works well with CSS in formatting HTML elements. The latter even started developing the first modern JavaScript engine, called V8, which compiles bytecode into native machine code.Today, JavaScript has plenty of frameworks and libraries to simplify complex projects, such as AngularJS, jQuery, and ReactJS.

Originally run on the client-side, the JavaScript implementation has branched out to the server-side after the Node.js development ‒ a cross-platform server environment built on the Google Chrome JavaScript V8 engine.While it caters to web-based programs the most, JavaScript programming features have other implementations in different areas. Web and Mobile AppsThe development of JavaScript frameworks, consisting of JavaScript code libraries, allows developers to use pre-written JavaScript code in their projects.
