Used it to explain stuff during my full stack bootcamp. It is immensely helpful when you have an idea of what you don’t know but are unsure what question you need to ask to find the answer. Even better when you know what function you need from a different language but don’t know what it’s called and has some esoteric name you cba to remember.
If a libraries docs are indexed it also helps quickly find the method you need to implement.
LLMs will likely always have a place as a supporting technology during and after education.
