JavaScript is a free, high-level programming language created by Brendan Eich in 1995 and standardized as ECMAScript. Originally built to add interactivity to web pages, it now runs everywhere: browsers, servers, mobile apps, and desktop software. It's dynamically typed and supports functional, object-oriented, and event-driven styles. Yearly updates have added features like async/await, modules, and optional chaining. Its quirks around type coercion and equality still trip up newcomers.
