Frequently asked questions

How does the JavaScript formatter work?

The formatter parses your JavaScript and rebuilds it with proper indentation, line breaks, and consistent spacing. You can choose between 2-space or 4-space indentation.

Does it support ES6+ syntax?

Yes, the formatter handles modern JavaScript including arrow functions, template literals, destructuring, async/await, and other ES6+ features.

Will formatting change code behavior?

No, formatting only affects whitespace and code structure. The functionality and output of your code remain identical after formatting.
