Frequently Asked Questions

What is JavaScript formatting and why is it needed?

JavaScript formatting adds structural indentation, proper line breaks, and space padding to raw or compact scripts. This makes complex logic, functions, and object structures readable for debugging and maintenance.

What indentation options are supported?

You can select 2 spaces, 4 spaces, or Tab indentation depending on your coding guidelines or team style conventions.

Does the JS formatter execute my code?

No. The formatter parses JavaScript text syntactically to add proper spacing and line feeds. It never executes or evaluates your JavaScript code.

Can I format modern ES6+ JavaScript code?

Yes. The formatter supports ES6+ features including arrow functions, template literals, destructuring, class definitions, async/await keywords, and modules.

Is my JavaScript code private and secure?

Yes. All JavaScript formatting and code processing occur 100% inside your local web browser. Your source code is never sent to remote servers or stored anywhere.

What is the difference between JS Formatter and JS Minifier?

JS Formatter expands and aligns JavaScript code with clear line breaks and indentation for human readability, whereas JS Minifier compresses code to shrink file download size.
