JavaScript
A core client-side programming language used to create interactive, dynamic web pages, widely supported across hosting environments and essential for modern sites.
JavaScript is the programming language that adds life and movement to websites. It allows developers to create interactive features such as dropdown menus, animations, and live updates without reloading the page. Combined with HTML and CSS, it forms the backbone of modern web development. JavaScript runs directly in the browser, but it can also power servers and apps using frameworks like Node.js or React. Nearly every website you visit relies on it in some way. Without JavaScript, the web would be static, dull, and far less engaging for users.
