Frequently asked questions
What library powers this formatter?
Prettier 3, loaded from the jsDelivr CDN, the industry-standard JavaScript formatter. Your code is formatted locally in your browser.
My code has an error. What happens?
The tool shows you Prettier's exact error message instead of guessing. Fix the syntax error and format again.
Does it support TypeScript and JSON?
Yes. Use the parser dropdown to pick JavaScript, TypeScript, or JSON before formatting.
