Angular is a JavaScript open-source front-end web application framework. It is used for building MVC based applications. This framework is used for developing mostly Single Page applications.  It uses code templates written in HTML in order to perform a particular function or command.

The framework is built on the concept of MVC (Model-View-Controller). This pattern is based on splitting the business logic layer, the data layer, and presentation layer into separate sections. Models are used to represent your data. Views are used to represent the presentation layer which is provided to the end users. The Controller represents the layer that has the business logic. User events trigger the functions which are stored inside your controller. The user events are part of the controller.

Angular.js keeps the data and presentation layer in sync. Thus you don't need to write an additional JavaScript code to keep the data in your HTML code and your data later in sync. Angular can take care of routing which means moving from one view to another. This is the key fundamental of single page applications. This helps to move different functionalities in your web application based on user interaction but still stay on the same page.

It extends HTML by providing its own elements called directives. Directives are markers on a DOM element that tell AngularJS's HTML compiler to attach a specified behaviour to that DOM element. These directives help in extending the functionality of existing HTML elements to give more power to your web application.

These are some of the components of Angular.js

Modules: 

The module is a set of functions defined in a JavaScript file. Module divides an application into small and reusable components.

Directives: 

Directives indicate the compiler to associate a behaviour to the DOM element or modify it. Angular JS contains several directives such as ng-app, ng-controller, ng-view, ng-if, etc.

Expressions: 

It indicates a data binding in HTML. These expressions can be added to the HTML templates.

Controller: 

It is a JavaScript object constructor function that controls the AngularJS applications.

Scope: 

It is a JavaScript object that acts as a bridge between the Controller and the View. It is the source of data in AngularJS. Each data manipulation and assignment takes place with the help of the Scope object.

Data Binding: 

It coordinates model and view about any changes in either of these two.

Filters: 

These let you display the formatting of data on DOM and extend the behaviour of directives and binding expressions. Filters format the values or apply specifically.
