“Tell me how MVC works” is far better than reading MDN documents. “Show me how to build a basic command line application.” “Tell me about polymorphism and give me some examples on how to use it.” “Teach me the basics on how to build an authentication system.” An LLM is great at that.
Reading MDM docs doesn’t put any context around what you’re reading. And reading all the docs doesn’t teach you any more than reading a dictionary teaches you how to write.
Docs are a reference, they really aren’t a place to start when you don’t know what you’re reading. Besides it’s boring.
You don’t learn Russian by reading Tolstoy. You read Tolstoy once you have some idea of what the words mean.
