JavaScript Formatter

How It Works

This basic JavaScript formatter processes your code character by character, tracking the nesting depth of braces, brackets, and parentheses. In beautify mode, it adds line breaks after opening braces, semicolons, and closing braces, and applies proper indentation based on the current nesting level.

The formatter respects string literals (both single and double quoted) and template literals, ensuring characters inside strings are not treated as structural elements. Comments are also preserved during beautification.

In minify mode, the tool removes comments, collapses whitespace, and removes unnecessary line breaks. Note that this is a basic formatter and may not handle all edge cases of complex JavaScript. For production use, consider dedicated tools like Prettier or ESLint.
