Can you be specific about what you're asking it to write?

I'm pretty confidient that I couldn't get it to implement a element in a web browser. I'm talking about C++ in WebKit or Chromium, not a custom element in HTML/JS. Let's say browsers wanted a new data-table element that natively implemented a scrolling window such that you registered events to supply elements and it asked for only the portion that were visible. I feel like those code bases are too complex for LLMs to add this (could certainly be wrong).

In any case, more concrete examples would help these discussions.

I can give a concrete example: I just asked ChatGPT (should have asked something more integrated into my editor), to give me JavaScript to directly parse meta data out of an MP4 file in JS in the browser. It gave my typescript but told me I should look at mp4box.

I spent 15-20 minutes getting a mp4box example setup (probably should have asked for that too). Only to find that I think mp4box does not get me the data I wanted.

So I went back to ChatGPT and asked for JavaScript because I was hacking in something like jsfiddle. It gave me that and it worked!

I then said I wanted the title and comments meta data as that was missing from what it gave me. That worked too, first try.
