lol that must be why all these websites look the same these days... bootstrap, possibly angular, etc. If they are drastically cutting down the time to make sites, then I guess you got to pare down as much as possible.
Overall, I feel I have a solid grasp of JS, but I still need to perfect my understanding of prototypes, closures and 'this.'
What technologies do you feel are necessary for the JS professional? I'll probably focus on 'base' things such as AJAX and jQuery in the near future and then pick up some framework. MongoDB and Node.js on the backend. I'll probably learn some SQL just to have that in my toolkit even though sql isn't often used in the JS stack.
