Original text: 7 Reasons to use AngularJS for developing your next web apps

In this era of e-commerce, every company is keen to expand its business through the Internet. This has also made the market for web developers extremely hot. According to a recent survey report, the total number of websites in the world has exceeded 876 million, and this number is still rising. There are also various platforms for web development on the market. For practitioners, the most important thing is to find the right option that suits them best. AngularJS was born in 2009 and has created a wave in the market since its debut. AngularJS is an open source web application framework that is mainly oriented to HTML (Hypertext Markup Language), CSS (Cascading Style Sheets) and JS (JavaScript).

As an open source web development framework, AngularJS is jointly created by Google and a community of developers. The main advantage of AngularJS is that it helps users implement necessary dynamic views in web applications. It allows everyone to implement multiple functions at runtime to extend the HTML vocabulary, thereby further improving code quality and speeding up the entire development cycle. It also uses a large number of customized instruction tags, dependency injection, filters, and RESTFUL API elements to ensure that we can adopt more best practices in web development work.

AngularJS is built on JavaScript, one of the most widely used and flexible programming languages ​​in the world. AngularJS provides users with a complete package for front-end applications. For web developers, AngularJS packages all the complex elements in the form of a framework, ensuring that users only need to directly access the most easily implemented functions, which is undoubtedly a great blessing for liberating productivity and simplifying workflows. In view of this, in order to help everyone understand the popularity and rich functions of AngularJS, we have sorted out seven reasons why AngularJS should be used when developing web applications - let's take a look below.

1) MVC Architecture

AngularJS uses the MVC architecture for web application development. To implement MVC, you only need to split your application, and AngularJS will take care of all the other work. MVC architecture refers to Model View Controller, which:

• Models are responsible for maintaining data.

• The view is responsible for displaying data.

• The controller acts as a bridge between the view and the model.

2) Instructions

You can use a variety of directives to change the specific behavior of HTML tags. This is a very powerful feature that allows users to create various customized tags. Using a directive tag will tell the compiler to add certain functions to the DOM element or even modify it. AngularJS also provides a large number of preset directives, and you can choose according to your actual needs.

3) POJO

Every object used in AngularJS is a POJO (Plain Old JavaScript Object), which means we no longer need to use additional getter and setter functions. POJO can provide us with all the standard JavaScript functions for object operations. It can help you remove and add properties from objects and skip certain objects as 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 difficulties we face when implementing the MVC architecture. Now we don't have to write getters and setters to implement the data model. In addition, directives are not part of the application code itself, so other parallel development teams can manage them. All of this minimizes the programming requirements for practitioners.

5) Testing with dependency injection

Our application is not complete without rigorous testing. In fact, testing has become an important means to ensure that there are no bugs in the delivered project. AngularJS has been built with testing in mind. Applications created with AngularJS are fully connected to dependency injection. You can easily inject sample data into the controller to test whether its output and behavior are as expected.

6) Client-side 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 type without making any changes to the backend. Therefore, we can use it to develop any application front end with confidence. In addition, since AngulaJS itself is client-side and can run on any browser that supports JavaScript, the difficulty of implementing application deployment becomes lower.

7) Flexible filters

Filters redefine values ​​before displaying them, such as changing the decimal places of a number, converting a string to uppercase, or adding pagination to a web page. These filters are very similar to directives and can be run as standalone functions, but are specifically designed for data transformation tasks. You can also create your own custom filters as needed.

Choosing the right platform is undoubtedly a crucial part of web development. Therefore, after reading this article, I believe everyone must have understood the power of AngularJS. Of course, this does not mean that AngularJS is enough to be the best option in every web development scenario. For example, it is not recommended to use AngularJS when dealing with high-intensity mathematical calculations, but it can indeed be an ideal development implementation method in most cases.

I'm sure you've considered other alternatives for web development in your work, or can come up with more reasons to prove the power of AngularJS. Please share your insights in the comments.
