# JavaScript Formatter & Beautifier

Format and indent JavaScript and TypeScript source code cleanly with customizable brace and quote preferences.

## What is JavaScript Formatter & Beautifier?

The JavaScript Formatter makes minified or poorly formatted code readable again. It adds line breaks after statements, indents blocks consistently with 2 spaces, 4 spaces or tabs, and normalises spacing around operators and braces. It is useful for reading third-party scripts, debugging production bundles, or tidying snippets before sharing. Formatting does not change what the code does.

## How to use JavaScript Formatter & Beautifier

1. **Paste JavaScript** — Paste the code or load the sample.
2. **Choose indentation** — Pick 2 spaces, 4 spaces or tabs.
3. **Copy the result** — The formatted code appears instantly.

## Frequently asked questions

### Can it restore original variable names from minified code?

No. Minifiers rename variables permanently; formatting restores structure and indentation, not names.

### Does it support TypeScript and JSX?

It formats standard JavaScript syntax; most TypeScript and simple JSX format correctly, but complex type annotations may not.

### Will my code run differently after formatting?

No. Only whitespace and line breaks change.
