Angularjs is created by Google Inc. and a community of developers. Its main advantage is to help users implement the necessary dynamic views in a Web application. It enhances HTML through native MVC (model-View-controller) functionality.

PS:MVC is a software architecture design pattern that separates performance from user interaction. Model---"Application of data + and data to interact with the method, view---" The data presented to the user, controller---"Bridge. A function that is used to add additional functionality to the scope of the view.

Ng-app---->> declares that all the content it contains belongs to this ANGULARJS application. Only elements that are contained by DOM elements with the Ng-app attribute are affected by ANGULARJS.

Ng-model---->> binds the Name property in the internal data model object ($scope) to the text input field. (PS: $scope object is a simple JavaScript object that can be accessed by the view and can interact with the controller)

<input ng-model= "name" type= "text" placeholder= "yourname" ><p>hello {{name}}</p>

Ng-controller---->> declares that all the elements it contains belong to a controller.

<div ng-controller="textcontroller">    <input ng-model="name  " type="text">    <p>hello {{name}}</p></div>

Scope: The glue between the view and the controller. That is, the view model.
$rootScope is the topmost of all $scope objects. An object that is a global scope.

Angularjs the tags used in the applied template:

directive: A property or element that enhances a DOM element to a reusable DOM component;

Value binding: Template syntax {{}} can bind an expression on a view.

Filters: Functions used in the view for formatting.

Form controls: Controls that are used to validate user input.
