The formatter runs in your browser and does not send code to a server. It uses braces, semicolons, commas, and comments to create readable lines and indentation.
No. It is a practical browser formatter without external packages. Use a project formatter for complex production code.
No. Formatting, minifying, syntax checking, and copying happen in the browser.
Yes. The check uses the Function parser, so module-only syntax can fail even when the formatted output is useful.
