My Thought about AngularJs

I used it for a half year.

First time I started it~ It was amazing because each input or text automatically know data is changed.

and I wanted know more and more ~

I will write what is very difficult to be skillful

Difficult Thing
  - understanding directive.
  - directives are very difficult to study
    scope, link, compile, restrict, transclude and so on...
  - communication controllers, controllers inherit
  - services

if I'm familiar with angularjs

Usefull Thing
  - project speed is upup ~
  - easy ajax network and databinding
  - custom common directives and i can use it
  - one page app
  - MVC structure
