It aims to moderate both the society and the mostly working on well known applications by providing a frame of reference for client-side model-view-controller (MVC) and model-view-view model (MVVM) architectures, along by all of components generally used in fruitful Internet applications.
AngularJS is the frontend case of the MEAN stack, consisting of MongoDB database, Express.js internet application server frame of reference, Angular.js itself, and Node.js runtime environment.
Let’s learn the structure of angularJS.
The View in an application really is a section which is rendered in a program through which client can associate or see whatever information has been asked. In an AngularJS application view is made out of directives, filters and data bindings. In any case, to make view straightforward and viable we don’t put the greater part of our code into the View. This helps us to separate code from view furthermore makes it simple to compose tests for the business rationale.
The Controller holds the greater part of our application logic in AngularJS. The Controller controls and readies the information into the frame with the goal that it can be rendered at the View. Practically what controller really does is, it gathers all of information into the representational frame furthermore takes from view and set into the Model in the wake of approving it. The controller is in charge of imparting the server code to get the information from a server utilizing Ajax asks for and send the information to back-end server from Views.
Model / View Model:
The most critical and head part of the MV* engineering is Model or View Model or $Scope.$Scope is a term which is presented in AngularJS. Model is the extension remaining amongst Controllers and Views. There can be a controller which we can tie to at least two views. Lets assume we have a controller doled out for an enrollment of clients, for this reason you can have an alternate view for desktop and another view for versatile.
Truly the Controller is clear about views and has no data about the views and correspondingly View is free of rationale actualized or information exhibit in the Controller. $scope goes about as the correspondence burrow between the Views and Controller.
Why Use AngularJS?
There are a ton numerous front-end structures accessible in the web world like Backbone, Knockout, Ember, Spline and so forth and every one of them have a few upsides and downsides. Be that as it may, With AngularJS you have to compose lesser code as it permits you to reuse parts. Additionally, it gives a simple method for two-way ties and reliance infusion. As AngularJS is customer sided so every one of these things are going on in programs, which gives you feel of standalone applications (Desktop application).
