What is controller?

in my first app angular help me to get title from main controller , but what is the controller ?

In a nutshell, the controller is where we get the data for the session. The controller puts the data in the same scope as our app instance.

so i can define variables in controller and save some data, and call it in view

So long as you maintain the data structure and syntax, yes.

<div class="main" ng-controller="MainController">

It’s because of the data connection (scope) that we can display the container in desired fashion.
