Introduction:

AngularJS is an open-source web application framework mainly maintained by Google and a collection of hobbyists, professional individuals and corporations.

Angular was first developed in 2009 by Misko Hevery. It was firstly supposed to be a “pay by the megabyte” service but later was turned into a open source library as it hadn’t have a substantial amount of subscribers.

It’s main purpose is to make the development and testing of single page applications more accessible and less time consuming.

It works as followed: The AJS framework first reads the HTML page that contains embedded tag attributes.

It works the attribute interprets them as directives to connect I/O parts represented by the standard JS variables.

Scopes:

$scope

In AngularJS a scope is a fundamental element of the development process and it is the same as in computer science.

In Angular, a scope is represents an object that itself can either be a in or out of scope in any given part of the program, and it follows the standard protocol of variables in JavaScript.

Bootstrap:

The AngularJS bootstrapper works in 3 steps after the DOM has been loaded:

I. Creation of a new Injector

II. Compilation of the directives that decorate the DOM

III. Linking of all directives to scope

BASED ON THE BOOTSTRAP SECTION ON WIKIPEDIA

ng-app

Declares the root element AngularJS application, under whom directives will be accustomed declare bindings and outline behavior.

ng-bind

Sets the text of a DOM element to the value of the expression. Any change to the variable ‘name’ is reflected inside the DOM.

ng-model

Similar to ng-bind, but establishes a two-way data binding between the view and the scope.

ng-model-options

Controls tuning on how model updates...
