JavaScript Minifier

The JavaScript Minifier is a web-based tool that reduces the size of JavaScript code by removing unnecessary characters (like comments and extra spaces). It runs completely in the browser, using vanilla JavaScript, so no server or internet is needed after loading the page.

Key Features:

1. Code Input Area
   • A textarea where users can paste or type raw, unminified JavaScript code.
2. Minify Button
   • On clicking "Minify", the script:
     • Removes all comments (// and /* */).
     • Strips extra whitespace and line breaks.
     • Minimizes spaces around symbols like {}, ;, :, and ,.
3. Download Button
   • Exports the minified code as a downloadable .js file named minified.js.
4. Copy to Clipboard Button
   • Copies the minified output to the user's clipboard with one click.
   • Useful for quick copy-paste into projects.
5. Output Area
   • A second textarea displays the resulting minified JavaScript.
   • It’s read-only to prevent accidental editing.
