FAQ
Does formatting change code logic?
No. Formatting only adjusts indentation and line breaks. JavaScript execution logic remains unchanged.
Does it support ES6+ syntax?
Yes. Properly handles arrow functions, template literals, destructuring, async/await and other ES6+ features.
Does it support minification?
Yes. Switch to minify mode to remove comments and excess whitespace for minimized JS output.
