Frequently Asked Questions

Does beautifying code change its functionality?

No, code beautification only changes whitespace, indentation, and line breaks. The logical functionality of your code remains exactly the same.

What's the difference between beautifying and minifying?

Beautifying adds whitespace and indentation for readability (development). Minifying removes all unnecessary whitespace to reduce file size (production). They're opposite operations.

Which indentation style should I use?

Most modern style guides recommend 2 spaces (Google, Airbnb for JS) or 4 spaces (Python PEP 8, Java). Tabs are preferred by some developers for accessibility reasons. Follow your team's or language's convention.
