Frequently Asked Questions
Is this a full JavaScript parser?
No. It is a lightweight formatter/minifier for quick cleanup. Complex modern syntax may need a full formatter such as Prettier.

For production builds, use a bundler or dedicated minifier. This tool is best for snippets and quick inspection.
Is code sent to a server?
No. Formatting runs locally in your browser.
