AngularJS is an open source front-end web application framework that is used mainly for developing single page applications and maintained by Google and a group of individuals and enterprises.
AngularJS was developed seven years ago in the year 2009 by Misko Hevery. It has undergone some major changes since its invention from versions 1.0 to enhance every part of AngularJS. After its version 1.3, the developers had announced that they were focusing mainly on the version 2.0. But the current stable release of AngularJS was done on January 2018 which was the version 1.6.9 which added many concepts of Angular in AngularJS, including the concept of component-based application architecture. The version 1.7 is scheduled to be out on June 30, 2018.
Two-way data binding: One of the most notable feature of AngularJS is two-way data binding between the selected element and the OrderProp model. It largely relieves the server of the templating responsibilities. In AngularJS, data is referenced using $scope objects. The concept of ‘$scope’ is very crucial in AngularJS as it detects changes to the model and modifies the HTML expression. The two-way data-binding and the nature of scope objects have led to the controller to be referenced as view-model. This is the pivotal reason for AngularJS to be popular as MVVM .

Dependency Injection: Dependency Injection is another important feature of AngularJS. It is basically nothing but a design pattern that implements inversion of control for handling dependencies. Using dependency injection, Angular brings traditionally server-side services which resultantly reduce the burden on the server. The prominent usage of dependency injections come in the field of testing and SPA (Single Page Applications). In case of testing, AngularJS allows the user to split the app into smaller modules that can have dependencies and lets the user import only the modules that he/she is interested in.
Allows expressing UI and reducing side effects: There are numerous benefits for declarative User interfaces. The extensions in AngularJS to HTML are done with the help of ng-directives. Some of the directives are ng-bind, ng-controller, ng-class, etc. By declaring the user interface, the chances for having side effects (An unexpected change that causes ruinous results) are reduced.

Provide Developers controls: In AngularJS, the user can easily split the functions into the MVC (Model View Controller) way. One of the most commonly heard complaints about MVC is that the various controls that it uses make it a bit complicated. AngularJS enables a feature namely ‘directive’ that helps in creating new HTML elements and attributes. For example, ng-class is a directive which is used to conditionally apply a class.
This graph is a clear indication of how successful the growth of AngularJS has been over these years. This level of popularity shows that it has not just gained the interest of an individual developer, but a wide range of audience. The audience look up to the AngularJS community with greater expectations and this was proven beyond doubt when the first batch of tickets of the second annual conference of AngularJS was sold out within a matter of two minutes.
