What Is Javascript?
JavaScript (JS) is a programming language that brings webpages to life.
It allows websites to respond, interact, and change dynamically — without reloading the page.
In simple terms:
| Without JavaScript | With JavaScript |
|---|---|
| A static webpage — just text and images | A dynamic webpage — buttons, animations, pop-ups, games, etc. |
| Looks nice but doesn’t react | Responds to user actions (clicks, typing, etc.) |
