Man, a few hours ago I was debating with some team mates about js frameworks. In the middle of this ocean of frameworks I keep going with ExtJS. And I'm very criticized about this. And today the discussion is as always - that it's a monster and I need try ember ou angular etc etc... But I keep using ExtJs happily focusing in my business and almost never worrying about why something not work and wondering how to use new new coolest javascript/css/html thing - I almost never touch html and css since I begin to use ExtJS. I'm happy and it's working.
