Frequently asked questions
Does formatting change how the code works?▼
No. Formatting only changes whitespace, indentation, and line breaks — the logic and behavior remain identical.
Can I use it for TypeScript?▼
Basic TypeScript formatting works in JavaScript mode. Type annotations may need manual adjustment in some cases.
Does minification remove comments?▼
The basic minification collapses whitespace and newlines. For full minification with comment removal, use a dedicated build tool like Terser.
