Created in 2009, Angular JS was a side project developed by two developers, Misko Hevery and Adam Abrons. These two originally started the project to build an end-to-end tool that allows web designers to interact with the frontend and backend. It is written in JavaScript language. The reason why Angular is popular in the market is that it consists of a set of ready-to-use modules. These modules simplify the building of single-page applications. AngularJS follows the MVC (Model View Controller). It is one of the popular software design patterns used to develop web applications.
The question here is what are Model, View and Controller in AngularJS?
<ul>
 <li>Model is the lowest level of the pattern which is responsible for maintaining data</li>
 <li>View includes the template (HTML) processed by Angular and the browser</li>
 <li>Controller includes the components and directives</li>
</ul>
Now, coming to the features of AngularJS. Out of its many features like data-binding and dependency injection eliminates the majority of the code currently one needs to write without using AngularJS. This all happens within the browser itself, making it an ideal partner with any server technology. To install all these features to your application you can hire angular js developer.
After knowing the features of AngularJS, let us have a look at its features and advantages:
 
Features of AngularJS
 
Below are the features that you can install in your application for getting the best out of AngularJS
Directives
 
Directives are markers on DOM (Document Object Model) elements like attributes, CSS, and more. It has a set of built-in directives that offers functionality to your applications. One can also create their own directives in AngularJS.
Some of the built-in directives include: ng-model, ng-init, ng-app.
 
Data-binding
Data-binding is the process of synchronization between the model and the view. Below are the two ways of data-binding in AngularJS:
<ol>
 <li>One-way Data-Binding/Basic data-binding</li>
</ol>
It is where the system takes the value from the data model and inserts it into an HTML element. The binding here is static in nature.
<ul>
 <li>ng-bind – Binds the inner text property of an HTML element</li>
 <li>ng-bind-template – It is the same as ng-bind allowing multiple templates</li>
 <li>ng-non-bindable - Highlights a region of the content for which data-binding will be not apply</li>
 <li>ng-bind-HTML - Creates data-binding using the inner HTML property of an HTML element</li>
 <li>ng-model - Creates a two-way data-binding</li>
</ul>
<ol>
 <li>Two-way data-binding</li>
</ol>
Here, when there is a change in the model, the change in data values gets reflected in the view. This is also known as “Dynamic data-binding in AngularJS”.
 
Scope
These are basically the objects that refer to the model. Scope is the binding part between the JavaScript (controller) and HTML (view). It is an object with the inbuilt properties and methods. It is available for both the controller and the view. A scope is used with the $scope in AngularJS.
 
Controller
The controllers control the entire data of AngularJS applications. These are regular JavaScript Objects. The applications of AngularJS are under the control of controllers. ng-controller defines the controller.
 
Services
A service is a function, or an object, that comes with the Angular JS. One can also make out services for the application of AngularJS. The scope of the service limits the application. There are around 30 inbuilt services available within AngularJS.
 
Examples:
 
$location: It is just an alternative to “window.location” that we use in HTML.
$http: &nbsp;It promotes a request to the server, and then allows the application to handle the response.
Filters
 
Filters are useful in Angular JS to format the data. One can also create their own filters by simply registering a new filter factory function with your module. Here are some of the filters provided: date, currency, filter, JSON, lowercase, uppercase, limitTo, number, orderBy.
 
Templates
It provides the viewer with the information from the controller and model.
 
Routing
It is helpful in switching views. In AngularJS, applications with the use of ngRoute modules can switch the applications to different pages without loading the entire application.
 
Deep Linking
It permits encoding the state of an application in the URL itself. Thus, you can bookmark it. One can restore the application from the URL to the same state.
 
Dependency Injection
It is a software designing pattern that deals with how components get hold of their dependencies. In AngularJS, an injector subsystem is responsible to create the component, resolving their dependencies, and to provide the dependencies to other components as per the requirement.
 
Advantages and Disadvantages of AngularJS
Following are the advantages and disadvantages of adopting AngularJS:
 
Advantages
Here are some advantages of AngularJS. To feature them in your application you can <a href="https://www.biztechcs.com/angularjs-development/">hire dedicated angular js developer</a>.
<ol>
 <li>Simple and Improved Design Architecture</li>
 <li>Lesser code to write</li>
 <li>DOM manipulation</li>
 <li>Code Reusability</li>
 <li>Improve Development Efficiency</li>
 <li>A code is Unit Testable</li>
 <li>Allow Dependency Injection</li>
 <li>Provision for filters</li>
 <li>Ability to create custom directives</li>
</ol>
Disadvantages
Here are some disadvantages of AngularJS you should go through once before using it.
<ol>
 <li>Not secure. To keep the application secure, you can install server-side authentication and authorization</li>
 <li>Not degradable. This means that if the JavaScript is disabled, then the viewer will see only the basic pages</li>
 <li>JavaScript support is mandatory to run the application</li>
 <li>Difficult to learn</li>
</ol>
 
Conclusion
After knowing the uses and advantages, now you know why it is so popular since its inception. Here, we also learned about the advantages and disadvantages of using it. So, what you can do now is first prepare a list of features you want for your application. And to add it to your applications, you can hire dedicated angular js developer.
