Why should I format my code?

Formatted code is easier to read, understand, and maintain. It follows consistent style conventions, making collaboration smoother. Minified code reduces file size for faster loading in production.

What is code minification?

Code minification removes unnecessary characters (whitespace, comments, newlines) from source code without changing its functionality. This reduces file size, improving load times and reducing bandwidth usage.

Does formatting change how my code works?

No. Code formatting only changes the visual presentation (indentation, spacing, line breaks). It does not alter the logic or functionality of your code in any way.

Yes. All code formatting happens entirely in your browser using JavaScript. Your code is never sent to any server, stored, or logged.
