Understand AngularJS: Definition, Features, and Comparison to ReactJS

What is AngularJS Misko Hervery and Adam Arbrons founded and developed AngularJS in 2009. Currently, Google is responsible for maintaining or managing. AngularJS is popular because it is a framework with a large fan community.

It is this ease of use and development that has driven the evolution of this type of JavaScript framework. Until now, it has been confirmed that it is running the latest version, namely 10.1.4.

What is AngularJS?

So what is AngularJS? AngularJS is a JavaScript framework handled by Google. It is based on the MVC (Model View Controller) pattern. Where the MVC technique serves as a framework for developing and cleaning applications.

Moreover, AngularJS can be understood as an open source or open source framework that is freely developed and implemented by anyone. As a result, this framework is used by a large number of developers worldwide for the development of applications and websites.

Google management ensures that this framework is trustworthy and performs well; Apart from that, it has an official website which makes it easy for users by offering user guides or instructions. AngularJS is a front-end framework for developing single-page applications (SPA).

Its dynamic nature facilitates the implementation and development of HTML on a larger scale. Incorporating them into an application or web page requires the use of directives or markers that correspond to elements of the Document Object Model.

AngularJS consists of several important components that affect the operation of the framework. The critical components are as follows:

The Ng-App in this section has a definition guide and links to HTML.

The Ng-Model converts HTML control input into an application data directive.

Ng-Bind adds HTML tag directives.

AngularJS Characteristics

Naturally, AngularJS uses a variety of easy-to-learn capabilities to speed up the process. These features are classified into two categories: main features and core features.

Key features of AngularJS include the following:

1. A framework for developing Rich Internet Applications using the efficient JavaScript programming language (RIA).

2. Using the MVC (Model View Controller) pattern, which simplifies the process of developing applications or developer options from a client-side perspective or point of view.

3. Automatically reads JavaScript code, making it easier to change the web browser that will be used.

4. AngularJS is a free framework with a strong community and a large number of admirers and users.

The main functions of AngularJS include the following:

1. Data Aggregation

In AngularJS, this function is used to synchronize or change the relationship between Model and View.

2. Purpose or Purpose

This is useful for copying objects that reference the Model between the Controller and the View.

3. Controller

A library of JavaScript functions built on top of the AngularJS framework.

4. Provider or Service

AngularJS services in the form of disposable objects are used to generate XMLHttpRequests in an application.

5. Filtration

A subset of elements in an array that can be applied and result in the creation of a new array.

6. Instruction

Directives, or element markers in the Document Object Model, can be used like custom HTML tags.

7. Template

Displays data from Controller and Model in one page with multiple views.

8. Routing

The act of changing views or switching.

9. Display Model View

The division of work and responsibilities of each individual will help the efficiency of the work process. By implementing a division of labor in the form of Model, Controller, and View (MCV), as well as an approach that is more like MVVM (Model-View-Viewmodel).

10. Deep Linking

Permissions can be allowed to encode programs in URLs and create bookmarks that return the previous state of the URL.

11. Dependency Injection

It features dependency injection, which makes testing and developing applications or websites easier for developers.

Functions in AngularJS

AngularJS’ goal is to be a framework for developing websites using JavaScript code. It performs various activities related to the development, creation and maintenance of websites.

Ease of management that allows developers to efficiently manage websites. As a result, the app is also free and open, which makes it easy for anyone who wants to run a website to enter it quickly.

Advantages of AngularJS

Of course, there are pros and cons to using AngularJS. Let me examine the benefits of using it on a website.

1. Make app development easier for developers by enabling them to handle Single Page Apps in a simple way.

2. Has a high level of interaction with HTML because of its ability to bind data to HTML.

3. Consists of reusable components.

4. It has a Dependency Injection feature, which allows developers to create components or programs that are independent of each other.

5. Ease of code generation to generate code more concisely and efficiently.

Naturally, among the advantages and disadvantages that exist are disadvantages or disadvantages in the form of:

1. Because security is not sufficient, it must always be guarded. In particular on the server and during authentication of applications or websites.

2. There is a significant degree of dependence on web browsers, related to web browsers.

ReactJS vs. AngularJS

When AngularJS was introduced in 2010, it quickly became the framework of choice for many developers. The MVC architecture and bidirectional data retrieval make data collection simple, and data coding is extensively documented.

However, AngularJS has a performance drawback. As a result, ReactJS emerged, rumored to be a superior JavaScript framework over AngularJS. Let’s compare the two frameworks.

The difference can be seen in many of the framework’s display features or services.

Data Binding

AngularJS performs data binding with the Document Object Model (DOM) in two steps, allowing the user to interact with the views and results of the model. When data binding occurs in both directions, the likelihood of website problems increases.

ReactJS performs data binding in one step, which simplifies implementation, and has minimal dependency, which reduces the likelihood of website failure.

Display type

AngularJS provides the MVVM (Model-View-View-Model) method view, which includes various utilities such as data linking, navigation, and HTTP support.

Whereas ReactJS requires the use of additional code such as Redux and Flux as navigation controllers.


AngularJS has the ability to offer services in the form of speed to load websites, thereby reducing website loading times. As it includes a client-side view service, it improves the loading speed of the website.

ReactJS leverages DOM services related to website performance to speed up page loading on websites.

Templates and Directions

AngularJS works with the DOM via directives, just like any other directive, such as ng-bind, ng-app, and others. In addition, in this case, it is possible to add new directives.

Since ReactJS doesn’t have templates that are frequently used on websites, the templates developed are defined through direct writing.


AngularJS makes it easy to add a level of scalability to a website.

Although ReactJS is not as scalable as the VueJS framework, it is easier to test websites.

They become material for comparison and reference to choose the framework that will be applied to their website as a result of the explanations and comparisons mentioned above. Of course, both frameworks have an advantage in terms of performance.


  • AngularJS is a JavaScript framework with its own set of features and benefits.
  • It has the main and core elements that allow it to function.
  • In terms of framework selection, this framework is often used by a large number of developers around the world.
  • AngularJS is compared to ReactJS in other frameworks.
