How to Start?

It’s really easy to start AngularJS. Just need to download AngularJS JavaScript file, and add to your web page with a script tag: You can also add it from remote url (e.g. http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js).  Here is an example code, so you can see how it works.

Explanation of this Code:

Here I will use 3 types of directives of AngularJS  which are:

ng-app:  This directive will define the angular application, That means this ng-app directive is for initializing the Angular into the page.

ng-model: This directive binds/takes the value from HTML controls (input, select, text area) to application data.

ng-bind: This directive  display the application data to the HTML view.

You can see ng-app directive is declared into the body tag that means Angular  is initialized among whole web page.  and the ng-model directive is declared three times called (name, title, and comment) and which was binds by {{name}}, {{title}}, {{comment}}
{{name}} bind for ng-model="name",
{{title}} bind for ng-model="title",
{{comment}} bind for ng-model="comment"
