Frequently Asked Questions

What JavaScript features are supported?
The tool supports ES6+ features including arrow functions, template literals, destructuring, async/await, classes, modules, and basic JSX syntax.
Can I customize the formatting style?
Yes, you can configure indentation, spacing around operators and brackets, quote style (single/double), semicolon insertion, and brace placement.
Does it validate JavaScript syntax?
The tool performs basic syntax validation including bracket matching, incomplete statements, and structural issues. For comprehensive linting, use dedicated tools like ESLint.
How does minification work?
Minification removes unnecessary whitespace, comments (optionally), and formatting while preserving code functionality. It doesn't perform variable renaming or advanced optimizations.
What about TypeScript support?
The tool handles basic TypeScript syntax but is primarily designed for JavaScript. For full TypeScript support, use specialized TypeScript formatters.
