Foire Aux Questions (FAQ)
Is my JavaScript code private?
Yes, completely. All formatting is done entirely in your browser using client-side JavaScript. Your code is never uploaded to any server or shared with third parties. Your source code remains fully private on your device.
Does it support JSX/React code?
The JavaScript formatter supports standard JavaScript including ES6+ features like arrow functions, destructuring, template literals, and async/await. For JSX and React-specific syntax, you may get better results using the dedicated formatting options.
Can I format minified JavaScript?
Yes, the formatter excels at beautifying minified JavaScript code. It will add proper indentation, line breaks, and spacing to make even heavily minified code readable again. Simply paste your minified code and it will be formatted automatically.
