Frequently Asked Questions
No — clicking Process shows a fixed message recommending real tools; your code isn't parsed, analyzed, or checked for errors by this page at all.
It's a placeholder pointing you to the real, standard tool for the job — real JS linting requires a proper parser (like ESLint's), which is a much bigger undertaking than this lightweight browser tool provides.
ESLint (eslint.org) is the standard JavaScript/TypeScript linter — install it via npm or use their online demo for a quick check without installing anything.
No — since no real linting happens, your pasted code isn't analyzed or sent anywhere; you can paste it here to keep it handy while you copy it to a real linter.
