What does “JavaScript” mean?

JavaScript

Oh okay, so this one's a bit specific —

JavaScript is a programming language used to make websites interactive and alive. Like, HTML gives a page its structure, CSS makes it look nice, and JavaScript makes things happen — buttons click, pop-ups appear, content updates without reloading the page.

So if you're on a website and you type something into a search bar and suggestions show up instantly? That's probably JavaScript doing its thing. Or when you click a photo and it opens in a little window instead of a new page — yeah, JavaScript.

It runs right inside your browser, so no extra setup needed to see it work. These days it's also used to build the back-end of websites, not just the front.

Basically, JavaScript is the language that brings a webpage to life.
