Javascript Formatter

What is JavaScript?
JavaScript (often abbreviated as JS) is a high-level programming language that enables interactive and dynamic behavior on web pages. As one of the core technologies of the web—alongside HTML and CSS—JavaScript powers everything from simple form validation to complex single-page applications.

Interactive User Experiences: JavaScript transforms static web pages into dynamic applications. It enables features like real-time content updates, form validation, interactive maps, animations, and responsive user interfaces.

Client-Side Execution: JavaScript code runs directly in the user's web browser via a built-in JavaScript engine. It can be embedded within HTML documents or loaded from external files, executing without server round-trips for immediate responsiveness.

Complementary Technologies: JavaScript works seamlessly with HTML and CSS. HTML provides structure, CSS handles presentation, and JavaScript adds behavior and interactivity—forming the foundation of modern web development.
