Options
Preferred line length before the formatter wraps suitable code. It is a formatting target, not a hard character limit.
Adds semicolons where the formatter’s JavaScript rules allow them. It does not change every statement ending.
Prefers single-quoted strings when they require no extra escaping; otherwise keeps the safer quote style.

Formats or minifies source without executing it. Minify removes formatting and, unless preserved, comments; it does not run compression transforms or rename identifiers. Equivalent behavior is not guaranteed.

How to use JavaScript formatter

Choose Format for readable source or Minify to remove optional whitespace and comments without compression transforms or identifier mangling. Review transformed code before deployment.
