Difference Between AngularJS And ReactJS

AngularJS and ReactJS are two popular frameworks in addition to the popular Ext JS enterprise JavaScript web framework. Developers around the world are utilizing them for building powerful web apps. Both of them are feature-rich. The frameworks offer all the tools to accelerate the development process. However, there are several key differences between AngularJS and ReactJS. In this post, you will find all the details.

What Is ReactJS?

ReactJS is an open-source JavaScript framework. Facebook introduced it in 2013. It enables you to conveniently build interactive user interfaces. ReactJS focuses on using reusable UI components. Hence, you can quickly create the front end of web apps. Also, it uses server-side rendering to provide high performance. As a result, it has become one of the most popular web frameworks on the planet.

What Are The Key Features Of ReactJS?

• Enables you to easily use third-party libraries
• Saves you a lot of time through reusable components
• The use of JSX brings simplicity and makes it easy to code applications
• Enables building rich UI to deliver a better user experience
• Virtual DOM enables quick rendering and facilitates fast performance
• Reusable React components result in a faster development workflow
• One directional data-binding delivers code stability

What is Angular?

AngularJS is another component-based Model-View-Controller (MVC) framework. Google released it on October 2010. It enables you to use HTML as a template language. Also, AngularJS allows HTML’s syntax to briefly express the application’s components. On top of that, it offers a suite of developer tools to develop and scale projects. As a result, AngularJS has become a great choice for building scalable web apps.

Why Are The Key Features Of AngularJS?

• Offers built-in support for AJAX, HTTP, and observables
• Provides strong community support
• Enables cross-platform development, suitable for building PWAs and desktop apps
• Offers a seamless experience to the developers with TypeScript
• Provides templates for helping you quickly create UI views
• Allows you to quickly add components, easily create tests, and instantly deploy apps with CLI
• Delivers speed and performance by optimizing the code

What Are The Key Differences Between AngularJS and ReactJS?

Both Angular and React are very powerful. They provide a robust set of features to enhance performance. However, they have some major differences.

Differences Between AngularJS and ReactJS: Do They Have Different Data Binding Methods?

AngularJS utilizes a two-way data binding method. It connects the Document Object Model (DOM) values to model data. Hence, the View changes as the data in the model change. Also, it significantly reduces boilerplate code. You don’t have to write additional code to provide continual View and Model synchronization.

On the other hand, ReactJS supports one-way data binding. Therefore, any change in component data is reflected in the view. Also, any change in the UI is reflected inside the component’s logic. One-way data binding provides singular behavior for your application. It significantly minimizes complexity. Hence, it will be easier for you to debug large React apps than the ones created with Angular.

Differences Between AngularJS and ReactJS: Do They Have Different Architectures?

AngularJS is based on the MVVM (Model-View-View-Model). Here, everything starts with a component. The structure consists of the Component, Properties, and Template. The Component defines and exposes properties to which the template can bind. It serves the role of ViewModel. The Properties are defined on the component. Thus, they become accessible to the template. They serve the role of the Model. And the template binds to the component properties. It serves the role of View.

On the other hand, ReactJS is based on Virtual DOM. Similar to AngularJS, everything starts with a component. However, its structure is different. It is comprised of Actions, State, and JSX. They serve the roles of Controller, Model, and View. Actions are JavaScript functions that react to the user interactions originating mainly from the JSX. State gets dispatched by the Action. And JSX binds to the state received from the action.

Differences Between AngularJS and ReactJS: Which One Delivers Better Performance?

Both AngularJS and ReactJS deliver similar performance in terms of loading and rendering. The loading and rendering times of AngularJS are 10 ms and 3 ms respectively. For ReactJS, the times are 7 ms and 6 ms.

However, ReactJS has an upper hand due to the use of Virtual DOMs. AngularJS uses a traditional DOM. Here, the DOM tree finds and updates every node interested in an event. It is a computationally heavy process. It requires analyzing and updating an entire tree structure at every change of state. As a result, you will face performance issues on apps having a large number of UI elements.

On the other hand, ReactJS uses Virtual DOMs. Here, the DOM doesn’t need to be updated at every instant the application state changes. Instead, it utilizes a Virtual Tree for making the DOM look like a new state. There is no need to recreate all of the DOM nodes. As a result, you get several key advantages, including a faster DOM update process and more dynamic data binding.

Differences Between AngularJS and ReactJS: Do They Support Dependency Injection?

Dependency injection refers to the technique of making a class independent of its dependencies. It is available on AngularJS. Hence, the framework can automatically find the appropriate injected objects. Here is an example of dependency injection in Angular:

import { Injectable } from '@angular/core';
@Injectable({
  providedIn: 'root',
})
export class HeroService {
  constructor() { }
}

However, ReactJS does not entirely support dependency injection. It has a global state for all the components. As a result, it does not comply with data immutability and the concept of functional programming. Nonetheless, you can use dependency injection on ReactJS by using different instrument modules, including Browserify and RequireJS.

Here is an example of dependency injection in React:

const name = 'Josh Perez';
const element = <h1>Hello, {name}</h1>;
ReactDOM.render(
  element,
  document.getElementById('root')
);

Differences Between AngularJS and ReactJS: Do They Support Directives?

Directives in AngularJS are your application’s template logic. They are written as attributes or tags. You use them to organize the code around the DOM. AngularJS has many standard directives, like ng-bind or ng-app. Also, it lets you create your own directives.

On the other hand, ReactJS doesn’t support any division for directives. However, it has many libraries for managing data flow such as Flux, Redux, Mobx, ReactN, and React-hooks. Therefore, it is much easier to build component trees on React.
