This article mainly introduces the seven major advantages of angularjs, because it is really convenient to use. If you want to see the shortcomings of angularjs, you can go to the article I recommend below. Now let’s take a look at this article about the advantages of angularjs

Let’s first look at the introduction of the seven advantages of angularjs:

AngularJS is an excellent front-end JS The framework has been used in many Google products. This framework has many features, the most core of which are: MVVM, modularity, automated two-way data binding, semantic tags, dependency injection, etc. Here are seven of the best features.

1.MVC architecture

AngularJS uses MVC architecture to develop web applications. To implement MVC, you just split your application and AngularJS manages the rest. The MVC architecture represents Model View Controller, where: the model is responsible for maintaining data -> the view is responsible for displaying data -> the controller connects the model and the view

2. Instructions

# The ## directive allows you to change the specific operation of HTML tags. This is a very powerful feature that allows you to create custom labels. Using directive tags tells the compiler to add certain functionality to the DOM element and even modify it. AngularJS also provides a large number of preset instructions, which you can choose according to your actual needs.

3.POJO

Every object used in AngularJS is a POJO (traditional JavaScript object), which means you don’t need additional getters and setters function. POJO can provide you with all standard JavaScript functions for object manipulation. It helps you remove and add properties from objects and skip certain objects if needed.

4. Ease of use

AngularJS has a rich feature set that makes the development process easier by reducing the need to write code. It eliminates the need for us to Various difficulties faced when implementing MVC architecture. To

implement the data model, you don't need to write getter and setter functions. Additionally, directives are not part of the application code, so they can be managed by other parallel development teams. All of this

minimizes the programming requirements for developers in development work.

5. Testing through Dependency Injection

An application is incomplete without rigorous testing. In fact, testing is an important way to ensure that there are no bugs in the delivered project. AngularJS already incorporates testing into the build process

. Using AngularJS to create applications is fully connected with dependency injection. You can easily inject sample data into the controller to check whether its output results and operation methods are as expected.

6. Client-Side Solution

AngularJS works on the client side, but is also compatible with desktop and mobile browsers. AngularJS can be used to create any project without making any modifications to the backend, so we can use it to develop the front-end of any application. In addition, since AngulaJS itself is client-side and can run on any browser that supports JavaScript, application deployment becomes easier.

7. Data binding

Typical DOM operations are to first find the corresponding dom node through id or class and then assign values to the dom node. This kind of work is very repetitive, and it is also necessary to ensure that the interface and JavaScript attributes are in the correct state when obtaining the data (for example, some DOM nodes are dynamically generated by JS and cannot be directly bound to the click function, etc.). When using Angularjs, you don't have to worry about finding dom nodes and dynamically generating dom nodes with js that cannot bind events. Using ng, you only need to write the events to be bound on the corresponding dom. As for data binding, the data of the model in the controller and the data of the view layer model are always consistent. (If you want to see more, it is recommended to go to the PHP Chinese website

Such as:

<html ng-app>  
<head>  
<script src="angular.js"></script>  
<script src="controllers.js"></script>  
</head>  
<body>  
<div ng-controller=&#39;HelloController&#39;>  
<input ng-model=&#39;greeting.text&#39;>  
<p>{{greeting.text}}, World</p>  
</div>  
</body>  
</html>

Copy after login

Controller code:

function HelloController($scope) {  
    $scope.greeting = { text: &#39;Hello&#39; };  
}

Copy after login

When controlling When the model data in greeting changes, the data in the view layer will change accordingly.
