Frequently Asked Questions
Will formatting change how my JavaScript works?
No, JavaScript formatting only changes whitespace and indentation. Your code will execute exactly the same way.
Can I format TypeScript with this tool?
Basic TypeScript will format correctly since it's a superset of JavaScript. However, some TypeScript-specific syntax may not format perfectly.
What about JSX code?
JSX code will generally format well, though complex JSX structures might need manual adjustments for optimal readability.
