I am kinda of outdated, but what I have been reading last couple weeks are all related to NodeJS. Yea, it probably been on the industry for many years, but I actually just started playing with it, but I think it is really impressive.
Yea, feel like now I can just do everything with Javascript to write a Web App. Thats pretty amazing, probably can reduce the learning curve a lot. PHP, Python.. yea I know all of those, but mostly I used on Server side Stuff, and then on Client Side I need to use Javascript.
BackboneJS also a very nice framework for MVC.
oh yea, with framework such as Phonegap, you can even write mobile app with JS and work as native app.
Seem everything merging to JS… No wonder it becoming the most popular language…
