What is AngularJS and Why Should You Use It?

Now it is winter outside and almost everybody has a Christmas mood. Moreover, it is one of the most favorite seasons of many people. But despite all of this one should not forget about work and self-development and it's time to talk about the new topic "What is AngularJS and why you should use it?" And now, let's discuss more important questions:

1. What is AngularJS?
2. What makes AngularJS different?
3. Why should you use it?

Let’s examine these questions in a little more detail.

What is AngularJS? 

AngularJS is an open-source JavaScript framework. It gives some great opportunities for creating synergistic sites. It was developed by Google and used by the majority of developers all over the world. It is important to add that this framework is one of the most popular and effective JavaScript frameworks. It is a basic framework planned to facilitate the development of a website's front-end. What gives popularity to this technology? One of the main reasons for the popularity of AngularJS is that it lets you use HTML as a model language. This framework expands the ability of HTML by enabling you to change various components of your web-page. According to experts, you can use AngularJS to establish any kind of app.

What makes AngularJS different?

This question becomes the main one today. Many people claim that static documents and active apps demand various approaches. AngularJS resolves different problems with data binding and code reuse. In a nutshell, this framework learns your browser's new structure through directives. The second reason for the popularity of AngularJS is the reality that it presents the highest level of generalization to the developers. It's no secret that AngularJS stays on the list of best known JS frameworks. As a result of its huge characteristics, AngularJS became so popular. 

Which websites can be created using AngularJS?

Some of the essential websites that use the adaptability of AngularJS are:

1. Upwork
2. Netflix
3. Lego
4. PayPal

AngularJS supports other webpages as well.

Advantages and disadvantages of AngularJS

Advantages	Disadvantages
1.     It is often said that this framework gives the ability to build a Single Page Application in a very clear and supportable way.	1.     Not fasten − Being JavaScript's unique framework, an application written is not safe. Server-side verification and support are needed to hold an application firm.
2.     It is clear from the facts that in AngularJS simple HTML pages are shown, and what is more that control devices addressed in JavaScript do the business processing.	2.     Not decomposable, if your application user damages JavaScript then the user will just understand the central page and nothing more extra.
3.     It presents data binding ability to HTML so providing the user with a rich and dynamic involvement.
4.     Reusable elements are provided.

AngularJS Directives

The AngularJS framework can be separated into three major parts:

ng-app − this directive defines and links an AngularJS application to HTML.

ng-model − this directive binds the values of AngularJS application data to HTML input controls.

ng-bind − this directive binds the AngularJS Application data to HTML tags.

Why should you use AngularJS?

There're many web technologies available but AngularJS is quite popular. Let’s explore some of the features that give AngularJS a competitive advantage over other choices:

1. Simplified Model-View-Controller (MVC)

In a standard MVC application, the model layer controls data, and the view layer presents it. A controller combines these two layers. Nearly every JavaScript framework deals with the MVC in two components. It is often said that AngularJS explains the MVC implementation in your development. AngularJS automatically connects various MVC components, and it takes less time to develop your code.

2. Dependency Injection

It is important to add that this framework has a built-in dependency injected control-command that supports a developer by making the application simpler to explain, learn, and test.

3. Code Reusability

Clearly, AngularJS supports HTML grouping to reuse its elements. Additionally, developers can reuse the same code which has been already generated. Code-reusability saves time and results in more active development while securing uniformity of similar web applications.

4. Filters

It is clear from the facts that filtering in the AngularJS framework is adopted to manage data before it creates the top layer of the application. How to organize filtering? Filtering in AngularJS can be performed simply by a subset of an array to clean out additional information. Additionally, you can perform difficult data changes like pagination by changing various parameters of your code.

5. Templates

You must admit that various templates are prepared in AngularJS to improve your code immediately. You can increase the functionalities of plain HTML templates by combining instructions. Templates allow designers and developers to work together while creating a website.

If you haven’t learned AngularJS yet, you need to start. I recommend this framework. This structure is composed of a firmly set of toolsets that will help you make well-structured, expensive client-side applications in a modular way with shorter code and top adaptability. Of course, you can also build your directives, craftwork reusability elements that meet your requirements.

Conclusion

Different changes in the business environment made developers use various methods to meet the market demands. You must be certain that Angularjs framework supports integration testing and unit testing to simplify the testing of web apps. I hope you have received some new information about this theme. I tried to highlight the most important facts, which can be useful for you. And for more creative work, I suggest you can hire an Angularjs Development Company.
