    JavaScript (JS) is a versatile, lightweight, interpreted (or just-in-time compiled) programming language with first-class functions. It is widely known as the scripting language for web pages, but it is also used in many non-browser environments such as Node.js, Apache CouchDB, and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, single-threaded, dynamic language that supports object-oriented, imperative, and declarative (e.g., functional programming) styles.

    Key Features of JavaScript

    JavaScript's dynamic capabilities include runtime object construction, variable parameter lists, function variables, dynamic script creation (via eval), object introspection (via for...in and Object utilities), and source-code recovery (JavaScript functions store their source text and can be retrieved through toString()). It is important to note that JavaScript is not the same as Java; they have different syntax, semantics, and use cases.
