AngularJS provide three useful services which it uses internally., $compile, $parse, $interpolate. These service are mainly used to evaluate expression and rendering UI.

At the heart of angularjs is data binding, in this blog post we will see how angular implements this and what is the life cycle of angular scope. This is very important to understand if you want to optimize your application for performance.

We know angularjs has a data binding between scope and html, which means what ever data changes we make in our controller scope it gets reflected to our html. But things change when we use a 3rd party library or external events to make changes to our scope.
