I recommend Udacity or any other type of structured learning. I personally have a difficult time learning something unless it's in a classroom-type environment or a virtual classroom.

When I was catching up to development trends bootcamps weren't around. I went to a ton of Meetups and I didn't understand a lot of what I heard. I'd note things and research them and hearing certain concepts over and over paid dividends when I was eventually able to make connections in my head.
