ChatGPT benefits from how abundant languages like Javascript and Python are. When you start diving into the lesser used languages, the struggle becomes real. Even worse if there have been substantial breaking changes in the past ~2 years.
TypeScript happens to be my current strongest language. I picked Phaser since I wanted to learn the ins and outs of building the game and not need to worry about the language I was writing in. This was also helpful because GPT-4 would still get small things wrong with the TypeScript, but I was able to easily fix those without needing to ask it.
If I had tried this in Unity and C# (which I don't know at all), I'd still be figuring out the standard library.
I generally recommend learning one new thing at a time when building something new.
