AngularJS

AngularJS is a Java script open-source front-end structural framework that is mainly used to develop single-page web applications. It is a continuously growing and expanding framework which provides better ways for developing web applications. It changes the static HTML to dynamic HTML. Its features like dynamic binding and dependency injection eliminate the need for code that we have to write otherwise. AngularJS is rapidly growing and because of this reason, we have different versions of AngularJS with the latest stable being .

Why use AngularJS?

• Easy to work with: All you need to know to work with AngularJS is the basics of HTML, CSS, and Javascript, not necessary to be an expert in these technologies.
• Time-saving: AngularJs allows us to work with components and hence we can use them again which saves time and unnecessary code.
• Ready to use a template: AngularJs is mainly plain HTML, and it mainly makes use of the plain HTML template and passes it to the DOM and then the AngularJS compiler. It traverses the templates and then they are ready to use.

Key Features: There are numerous features of AngularJS that contribute to creating efficient applications.

• Model View Controller(MVC)

  An architecture is basically a software pattern used to develop an application. It consists of three components:

  • Model: This component consists of a database & is responsible for managing the data & logic of the application. It responds to the request made by the View component & the instruction given by the Controller component, in order to update itself.
    • View: This component is responsible for displaying the application data to the users. The View is basically the user interface that helps to render the required data to the user, with the help of the AngularJS expressions.
    • Controller: This component is responsible for communicating & interacting between the Model & the View Component, i.e. its main job is to connect the model and the view component. It helps to validate the input data by implementing some business logic that manipulates the state of the data model.

• Data Model Binding: Data Binding in AngularJS is a two-way process, i.e the view layer of the MVC architecture is an exact copy of the model layer. You don’t need to write special code to bind data to the HTML controls. Normally, in other MVC architectures, we have to continuously update the view layer and the model layer to remain in sync with one another.
• Templates: The main advantage of using AngularJS is how it makes use of the templates.
• Unit Testing ready: The concern of Google’s designer was not only to develop Angular but also to develop a testing framework  which helps in designing unit tests for applications.
