AngularJS (commonly called “Angular” or “Angular.js”) is a complete JavaScript-based open source front-end web application framework maintained primarily by Google and by a multitude of individuals and corporations to address many of the challenges . found in single page application development. The JavaScript components are all in one Apache Cordova, the framework used to develop cross-platform applications on the wing.
It aims to moderate both society and the majority of those working on popular applications by providing a framework for model view controller (MVC) and model view model (MVVM) architectures on the user side. customer, along with all components. it is generally used in fruitful internet applications.
AngularJS is the interface case of the MEAN stack, which consists of the MongoDB database, the Express.js Internet Application Server framework, Angular.js itself, and the Node.js runtime environment.
Let’s learn the structure of angularJS.
Points of view:
The View in an application is really a section that is presented in a program through which the client can associate or view any information that has been requested. In an AngularJS application, the view is made up of directives, filters, and data bindings. In any case, to keep the view simple and workable, we don’t put most of our code in the View. This helps us separate the code from the view and also makes it easier to compose tests for business logic.
Controller:
The controller contains most of our application logic in AngularJS. The Controller controls and reads the information in the frame so that it can be rendered in the View. Pretty much what the controller actually does is collect all the information in the rendering frame and remove it from the view and put it in the model after it’s passed. The controller is in charge of imparting the server code to get the information from a server using Ajax requests and send the information to the backend server from Views.
Model / View model:
The most critical and main part of MV* engineering is Model or View Model or $Scope. $Scope is a term that comes around in AngularJS. Model is the remaining extension between Controllers and Views. There may be a controller that we can bind to at least two views. Let’s say we have a distributed controller for a client enrollment, so you can have an alternate view for desktop and another view for mobile.
Truly, the Controller is clear about views and has no data about the views and consequently the View is free from updated justification or information display in the Controller. $scope acts as the correspondence burrow between the Views and the Controller.
Why use AngularJS?
There are a lot of front-end frameworks available in the web world like Backbone, Knockout, Ember, Spline, etc., and each of them has some advantages and disadvantages. Be that as it may, with AngularJS you have to write less code since it allows you to reuse parts. Also, it provides a simple method for two-way linking and dependency infusion. Since AngularJS is client-side, all of these things happen in programs, giving you the feel of stand-alone applications (desktop app).
