## Read small scripts again

Apply lightweight indentation to JavaScript snippets used in static pages.

## Useful for debugging

Formatted scripts make event handlers, fetch calls, and form logic easier to inspect.

## Prepare for safer edits

Use readable JavaScript before asking an agent or teammate to modify behavior.

## How to use JS Formatter

Make small scripts readable before debugging events, selectors, fetch calls, or form behavior.

1. **Paste JavaScript** — Add the snippet or small file you need to read.
2. **Format it** — StaticX returns a more readable version with indentation.
3. **Review logic** — Check events, selectors, URLs, and error handling before using it.

## Readable scripts are easier to trust.

Static sites often use small scripts for forms, navigation, embeds, or UI toggles. When those scripts are copied or generated, readability matters.

Formatting makes the code easier to audit, but it does not guarantee behavior. Test the page before publishing.

## Script review checkpoints

- **Good for snippets** — Use it for inline scripts and small files, not complex application bundles.
- **Check selectors** — Formatted code makes DOM selectors and event targets easier to verify.
- **No transpilation** — It does not convert TypeScript, JSX, or unsupported syntax.

## FAQ

### Will JS Formatter make code production-ready?

No. It improves readability. You still need testing and review.

### Can I format minified snippets?

Yes, especially before debugging or editing them.

### Should I paste API keys?

No. Public JavaScript should never contain private keys or tokens.
