I had a desire to help a coworker debug a javascript problem the other day. I do not interact with javascript very often. I pasted ChatGPT the function and asked it specific questions about how it was doing some things and it answered correctly. It also found an edge case where it could get stuck in a loop but we weren't actually hitting that issue.

It was right every time.

It is not a stupid useless tool. It does not "hallucinate" everything.
