About JavaScript Formatter
Format with Prettier Babel
The formatter uses Prettier's Babel parser, so it is suited to standard JavaScript snippets, copied browser code, and small module fragments. Syntax errors are reported before the tool returns a formatted result.
Review before minifying
Use the formatter when you need to inspect control flow, copied snippets, or generated code before passing it to a minifier. Readable formatting makes it easier to catch accidental globals, missing braces, and pasted debug statements.

What does this JavaScript formatter do?

Can I customize the indentation?
Yes, pick 2 or 4 spaces, or tabs. Most JavaScript style guides recommend 2 spaces.
Does it support TypeScript?
This tool formats standard JavaScript. TypeScript syntax may also work for common patterns, but for full TypeScript support, consider using a dedicated TypeScript formatter.
