When I decided to focus on a new technology I really wanted to be somewhere where all the "cool" things are happening. I ended up in the world of JavaScript and really have not looked back. If you are undecided have a look here http://githut.info/ http://githut.info/ as well as look at your local job market. I like to attend hackathons so being able to leverage a massive developer community is key to any technology I will bet my career on. Even now I'm pushing myself beyond JavasScript to use typescript as it brings a maturity to JavaScript I felt was lacking. The important thing is that I feel that there is so much community investment into being able to do things in JavaScript that it enables me to focus on deliverables.
