The best answer is always going to be a mix, which works for you. And each language you learn will provide more experience at learning. That said, and merely providing examples: Find the koan collection for each language. Pretty good for syntax and peculiar idea demonstrations. Not so good at project design. "build it as quickly as possible" and when you hit a roadblock start googling to find out how someone else got past it. Thats a PITA, surely there exists a library for that? Also blog posts / podcasts by devs for devs and read between the lines a bit. Not so much what are they specifically talking about but more generally. Nobody talks about XYZ and nobody mentions solutions to ABC, but everyone's got an opinion about DEF and GHI.
