JavaScript Error Explainer

omnial/javascript-error-explainer

Explains a JavaScript error message in plain English, given the error text and a short note on where it happened: the error's type, what it means, its likely root cause, a list of suggested fixes described in words, advice on preventing it, related error messages and search terms for finding more help. Written by a language model; code samples are not returned. Your input is sent to an outside service for processing; remove secrets and personal data first.
