In this article, the editor introduces in detail "what are the characteristics of angularjs", the content is detailed, the steps are clear, and the details are handled properly. I hope this article "what are the characteristics of angularjs" can help you solve your doubts? let's follow the editor's train of thought to learn new knowledge.

AngularJS was originally developed by MiskoHevery and AdamAbrons in 2009 and later became a project of Google. AngularJS makes up for the deficiency of HTML in building applications. It expands the HTML vocabulary in Web applications by using directives structure, so that developers can use HTML to declare dynamic content, which makes it easier for Web development and testing.

AngularJS function: AngularJS is a HTML designed specifically for applications.

AngularJS makes it easier to develop modern single-page applications (SPAs:SinglePageApplications).

1AngularJS binds application data to HTML elements.

2AngularJS can clone and repeat HTML elements.

3AngularJS can hide and show HTML elements.

4AngularJS can add code "behind" the HTML element.

5AngularJS supports input validation

The main features of Angularjs's so-called next-generation web applications are as follows:

1.MVC architecture

AngularJS uses the MVC architecture to develop Web applications. To implement MVC, you simply split your application and the rest is managed by AngularJS. The MVC architecture represents the model view controller, where:

The model is responsible for maintaining data

The view is responsible for displaying data

The controller connects the model to the view

two。 Instruction

The directive allows you to change the specific operation of the HTML tag. This is a very powerful feature that allows you to create custom tags. Using instruction tags tells the compiler to add some functionality to the DOM element and even make changes to it. A large number of preset instructions are also available in AngularJS, 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 getter and setter functions. POJO can provide you with all the standard JavaScript functions for object manipulation. It helps you remove and add properties from objects and skip some objects as needed.

4. Easy to use

AngularJS has a rich feature set that makes the development process easier by reducing coding requirements, eliminating the challenges we face when implementing the MVC architecture. To implement the data model, you don't need to write getter and setter functions. In addition, instructions are not part of the application code, so other parallel development teams can manage them as well. All these reduce the programming requirements of developers to the greatest extent.

5. Testing by dependency injection

Applications that have not been rigorously tested are incomplete. In fact, testing is an important way to ensure that there are no errors in the delivery project. AngularJS has included testing during the build process. Using AngularJS to create an application that fully interfaces with dependency injection, you can easily inject sample data into the controller to check whether its output and operation are in line with expectations.

6. Client solution

AngularJS works on the client side, but it is also compatible with desktop and mobile browsers. AngularJS can be used to create any project without making any changes to the back end, so we can use it to develop any application front end. In addition, because AngulaJS itself belongs to the client and can run on any browser that supports JavaScript, the implementation of application deployment becomes less difficult.

7. Flexible filter

The filter redefines the value before it is displayed, such as changing the decimal place of the value, converting the string to uppercase, and so on. These filters are very similar to instructions and can work as independent functions, focusing only on data conversion tasks. You can also create custom filters according to your own needs.
