What is JavaScript? A Simple Guide for Kids
Learn what JavaScript is and why it powers websites and games.
JavaScript is a programming language that makes websites interactive. When you click a button, play a web game, or see animations, JavaScript is often working behind the scenes.
Unlike HTML (structure) and CSS (style), JavaScript adds behavior. It can change text, react to clicks, and store user progress.
