The Script Tag
Learn how the <script> tag connects JavaScript to your HTML page — and why where you place it matters more than you think.

Plugging JavaScript into HTML
You've been writing JavaScript in the browser console, but real web pages need their JS code loaded automatically when the page opens. The `<script>` tag is how you connect JavaScript to an HTML document. Without it, your HTML page has no idea that any JavaScript exists. The browser reads your HTML file top-to-bottom, and when it encounters a `<script>` tag, it knows: 'Time to run some JavaScript.'
Think of it this way: The `
<script>` tag is like plugging in a power cord — it connects your JavaScript brain to the HTML body. Where you plug it in matters: plug a lamp into a socket behind the couch and it works fine, but plug a refrigerator into a weak extension cord and you'll blow a fuse.Learn more on MDN
