Is this as accurate as Prettier?

No. This is a basic character-level formatter, not an AST-based tool. It handles most simple cases but may produce incorrect indentation for complex code. For production use, use Prettier or ESLint.

Does Minify remove comments?

Yes. Both single-line (//) and block (/* */) comments are stripped during minification.

Does it handle template literals correctly?

Yes. The formatter tracks backtick string literals and does not treat braces inside them as structural indentation markers.

Is my data sent to a server?

No. The formatting runs entirely in your browser. Nothing is transmitted.

About JavaScript Formatter

Quickly readable JavaScript is important when debugging minified code or reviewing a snippet. This formatter applies a character-by-character parsing approach: it tracks string literals (single quotes, double quotes, template literals) to avoid treating braces inside strings as structural, increments indent depth on { and [, decrements on } and ], and adds a newline after each semicolon. The result is a basic but functional indentation that makes most JavaScript readable. Minify strips single-line comments (//), block comments (/* */), and collapses whitespace runs to a single space. For production code formatting with full AST-based accuracy, use Prettier or ESLint. This tool is best for quick inspection of minified snippets or small scripts. Runs entirely in your browser.
