What is AngularJS?

AngularJS is a JavaScript framework for organizing HTML code in a more structural, clear and succinct mode. This client-side technology provides easy and light code in order to make developing and even designing as a simple task. AngularJS eliminates most of redundant code specially in CRUD web application. It is a MV(Whatever you like) pattern and not just a MVC.
There are two kinds of accessories which help us to make a bridge between user interface and the core of business and data layer.
Library: These types are set of functions such as JQuery and whenever you use some of them ($.ajax) it will call related function to handle functions.
Frameworks: These types are specific structure for implementation application and developer have to follow these structure. Such as durandal and ember.
AngularJS has different approach to work out our needs, angular embeds new properties inside HTML tags such as “ng-model”, “ng-repeat” which are known as Directives in order to fade our barriers to match and transform data.
On the other hand AngularJS has mingled Ajax and HTML DOM in a good structure which I will describe it more as follow:
