Frequently Asked Questions

What does a JavaScript formatter do?
A JS formatter adds consistent indentation, line breaks, and spacing to minified or messy code. It makes code readable without changing behavior.
Does it work with modern JavaScript?
Yes, formatters support ES6+, async/await, and modern syntax. Some may have options for different style guides (e.g., 2 vs 4 space indentation).
Can I format TypeScript?
TypeScript is a superset of JavaScript, so basic formatters often work. For type-specific formatting, use a TypeScript-aware formatter.
