Limitations & Compatibility
Frequently Asked Questions
Is my JavaScript uploaded to a server?
No. The JavaScript formatting is executed entirely locally within your browser. KreateKode has zero backend processing for this tool, ensuring your source code remains private.
Does this tool execute my JavaScript?
Absolutely not. To guarantee complete security, your code is treated strictly as source text. We never use eval(), execute your scripts, or inject them into the DOM.
Does this tool support modern JavaScript features?
Yes! It fully supports modern ECMAScript syntax, including async/await, classes, template literals, optional chaining, nullish coalescing, and dynamic imports.
Can I format local .js files?
Yes. You can import local .js, .cjs, or .mjs files directly. They are loaded securely into browser memory for processing without ever being uploaded.
