Frequently asked questions
What languages are supported?
JavaScript, CSS, and HTML. The formatter detects curly braces and semicolons for JS/CSS, and angle brackets for HTML. For other languages, use language-specific formatters like Black for Python or gofmt for Go.
Does formatting change how code works?
No, formatting only changes whitespace and line breaks. The code behavior is identical. However, in rare cases with JavaScript ASI (Automatic Semicolon Insertion), adding line breaks can change meaning.
Why minify code in the first place?
Minified code loads faster — removing whitespace and shortening variable names reduces file size by 20-60%. Serve minified code to users but keep formatted source code in your repository.
What's the difference between formatting and linting?
Formatting fixes whitespace and style. Linting finds actual bugs and bad practices. Use both — a formatter (Prettier) for consistent style and a linter (ESLint) for code quality.
