I never considered memorizing the standard library having anything to do with coding. Same as memorizing where the books in a real library are to have anything to do with being able to read. Learning to code for me is learning the concepts like variable, loop, if, map, reduce, oop, sequence, array, function, return, lambda, monad, state, side effects, etc. Once you understand this, it doesn't matter what language and libraries get thrown at you, you'll be able to work with it. The rest you can read up in the documentation, and over time, as you say, you'll not need to look as much because you memorize it. But in my opinion that's just optimization after you learn coding.
