It is essentially what Zed Shaw propose in his "Learn Code The Hard Way" books. It definitely helps to type in everything and can be applied in almost anything we need to learn. It's this memorization trick teachers usually told us to do, basically rewrite the notes you've taken or things you need to remember. It's somehow boring to apply and while doing it you don't necessarily realize you are learning but it does work great. Then it's extended with programming where what you typed is used interpreted by your computer and turns results from what was typed.
