Yea, just copy/pasting code without already understanding it is a bad move.

If you deliberately drive GPT into a certain direction with the prompts about a specific topic and the model has been trained on the subject matter, its accuracy will be higher. If you ask GPT about a less popular language that it has little or no training on, its answer will likely be garbage.

I’ve been going through The Odin Project for full stack web development. It’s been great and is completely free.

I would advise against using Chat GPT or any other LLM; they “hallucinate” and can give you wrong information.
