What is AngularJS?
Now its an OpenSource client side JavaScript framework
created by Google
It designed for web developers and designers, who
needs to have more control over their web Applications
 For a web developer, it means having a rich feature
that allows them to add more value to the client side of
the applications
 AngularJS accomplishes a lot by embracing HTML,
JavaScript and CSS
AngularJS was originally developed in 2009 by Misko
Hevery and Adam Abrons at Brat Tech LLC, firstly
named as GetAngular

A better way to think about
angular is not to think about it
as framework but as HTML
compiler which allows you to
create your OWN DSL in HTML,
by attaching your own behavior
to any HTML element, attribute
or text. And by any I mean that
you can make up your own
names (outside those of HTML
spec)

1. Device: Need to adapt user interface to a wide variety of devices like laptops, mobile-phones, tablets running
on different operating systems
2. User Preferences: Diverse User preferences in viewing data ranging from spreadsheets to charts
3. Skill Sets: Resource skills rarely cover all aspects of development. A good graphic designer usually does not
have coding skills and vice-versa
4. Agility: Need to rapidly service new requests for information in a highly competitive environment faced by
enterprises

Features of AngularJS

The MVC pattern separates the application into 3 concerns
Model: The model is responsible for all behaviour and data of the
application. It is responsible for managing data, this included all
creation, retrieval, update and delete of data
View: This layer is responsible for the presentation of data and user
interaction
Controller: This component handles the interaction between the
View and the Model
Controller
Model View
JavaScript MVC framework

Separating Model from View (that is, separating data representation from presentation)
Easy to add multiple data presentations for the same data
Facilitates adding new types of data presentation as technology develops
Model and View components can vary independently enhancing maintainability, extensibility, and testability
