JavaScript Formatter
Beautify and format JavaScript code — expand minified JS with proper indentation and spacing.
About JavaScript Formatting
JavaScript formatting (beautification) takes minified or poorly-formatted code and adds consistent whitespace, indentation, and line breaks. This is essential for reading minified library code, understanding transpiled output, debugging code from stack traces, and reviewing third-party code. This formatter handles basic JS formatting — for full Prettier-level formatting, use the Prettier CLI or Prettier Playground.
FAQ
Should I use Prettier or ESLint for formatting?
Prettier handles code formatting (whitespace, line length, semicolons, quotes). ESLint handles code quality (unused variables, potential bugs, best practices). Use both together: Prettier for formatting, ESLint with eslint-config-prettier to disable ESLint formatting rules that conflict. Run both in your CI pipeline and as pre-commit hooks.
