What does "JavaScript" mean in programming?
JavaScript is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A dynamically typed, interpreted language that runs natively in web browsers and on the server via Node.js. JavaScript is the only language browsers execute directly, making it essential for frontend development. It is also used for backend APIs, mobile apps (React Native), and desktop apps (Electron).
