I'm a fairly experienced backend dev I built a few toy websites and I am casually interested in frontend stuff (like watching Fireship) so I thought I'd give it a try.
Long story short, it worked well. I have my app it has all the features I need I used it every day (till I lost 10kg) and I didn't write a single line of code.
However, the coding itself was unlike anything I had done before. I felt much more like a manager/Slave driver.
The core thing was structure structure structure. As soon as the task gets too large, GPT will produce something kind of right that is difficult to understand and impossible to extend. So your task is to split it up, and split it up. Also to apply judgment (it started out using objective-c haha). You have to ask it for alternative libraries. For reference. I relied a lot on something like: "In Python/C#/Rust I would do it like this".
But yes, my overall experience is that I think we are in for an exciting new time, but we are lacking a new coding paradigm.
