If typing is preventing you from learning then you should definitely practice. After I learned HTML and CSS I copy and pasted my way through JavaScript and Joubert for a long time. If I had invested the time to actually retype the code from the tutorial it really would have helped me learn faster.
Retyping code fro tutorials does many things. First of all, like taking notes in class typing it yourself helps you remember what is happening I your code. This makes refactoring and debugging 100 times easier. And second it helps you learn how to format code properly. Lots of editors do auto formatting for you but they aren't great with everything. So learning how to quickly get your code looking clean in a a big gain.
