Frequently Asked Questions
JavaScript formatting (beautification) adds proper indentation, newlines, and spacing to make code more readable and maintainable. It organizes functions, statements, and expressions in a clean structure without changing functionality.
Minifying removes unnecessary whitespace, newlines, and comments from JavaScript to reduce file size. This improves page load times and reduces bandwidth usage. The code executes exactly the same, but is more compact.
No! Formatting only changes the visual structure (indentation, spacing) without altering logic or functionality. Your code will work exactly the same after formatting. However, always test critical code after any transformation.
Yes! The formatter handles modern JavaScript syntax including arrow functions, template literals, destructuring, async/await, and ES6+ features. It preserves all modern syntax while formatting.
Yes! All formatting happens locally in your browser. We never upload your JavaScript to our servers. Your code, business logic, and any sensitive information remain completely private.
