What is JavaScript and how is it different from Java?
JavaScript is a lightweight, interpreted, and dynamic programming language primarily used to make web pages interactive. Despite its name, JavaScript has almost nothing in common with Java — they are completely different languages designed for different purposes. JavaScript runs directly in the browser (and on servers via Node.js), while Java is a compiled, object-oriented language used for building desktop apps, Android apps, and backend systems.
JavaScript is single-threaded, event-driven, and supports first-class functions. It follows the ECMAScript standard, with modern versions (ES6 and beyond) introducing powerful features like arrow functions, promises, and modules.
🇮🇳 Hindi में समझें
JavaScript एक programming language है जो web pages को interactive बनाती है। Java और JavaScript दोनों अलग-अलग languages हैं — नाम similar होने के बावजूद इनका कोई direct connection नहीं है। JavaScript browser में directly चलती है और pages को dynamic बनाती है।
