We have all gone through the struggle of choosing the best framework for the web application and often we get confused among these two popular options.

Startups, SMEs, and major firms seek to construct scalable web apps using capable frameworks.

Nowadays, AngularJS and ReactJS, are widely utilised in web app development, which makes it difficult for businesses to choose the ideal one. To help businesses understand the differences between AngularJS and ReactJS, I'll go over the topic of AngularJS versus ReactJS.

What is React?

Jordan Walke, a Facebook software engineer, invented the React library for frontend UI work in 2011. Yes, it's a library, but it's also referred to as a framework because expansion packages enable it to work as one. React (or React.js), unlike Angular, is based on JavaScript and uses a unidirectional data exchange approach that uses components rather than templates.

Many popular PWAs, social media networks, data dashboards, and cross-platform mobile apps all use React. React's wide market adoption is due to its simple formatting style and extensive component library.

Advantages of ReactJS

SEO friendly

Whereas all of the JavaScript frameworks are responsive to SEO, ReactJS excels in this area. You can execute ReactJS on the server, and the virtual DOM will be returned and rendered as a regular web page in your browser. You don't need to use any additional techniques!

JSX

It's a JavaScript-like syntax that looks like HTML. The markup and codes for JSX are combined in the same file. This implies that as you write references to your component's functions and variables, code completion assists you. When comparing AngularJS to ReactJS, the latter's string-based templates have the standard drawbacks: no code colouring in many editors, restricted code completion, and run-time failures. As a result, ReactJS has the upper hand.

Great User Interface

Unlike AngularJS, React Native is significantly more focused on the user interface. It uses JavaScript interactions between the device's native environment and ReactJS Native to provide your users with a highly responsive interface. As a result, the application's load time increases, and it runs more smoothly with fewer interruptions.

Highly efficient

React.js creates its own virtual DOM where you can store your components. Because ReactJS evaluates what changes need to be performed in the virtual DOM in advance and updates the DOM-trees accordingly, this technique allows developers a lot of flexibility and remarkable performance advantages. In React js development, developers avoid inefficient DOM operations and perform updates quickly.

Disadvantages of using ReactJS

Here, are few cons of using ReactJS

  • Integrating Reacts with a popular MVC framework like Rail necessitates a lot of setup.
  • Users of this framework would need to be well-versed in the integration of the user interface with the MVC framework.

What is Angular?

Angular is a frontend framework for JavaScript (JS) that uses the TypeScript language and was published by Google in 2010. It was created by Miško Hevery and Adam Abrons as a JavaScript-based AngularJS to assist programmers in creating dynamic content web applications using HTML templates.

The Angular 1.8.2 version, which was released on October 21, 2020, is a stable release. Because of an improved method for two-way data binding and the addition of component-based design, it can work up to 5-10 times faster.

Angular is used by many companies worldwide to create large-scale web applications like e-commerce, booking platforms, and Progressive Web Apps (PWAs), which turn a website into a smartphone app. Because of its Google support and coding capability, it remains one of the most used JavaScript frameworks.

Advantages of using AngularJS

Easy Decision Making

Because AngularJS is a full-fledged MVC framework, it comes with built-in opinions and capabilities. AngularJS makes it easier to get started without getting overwhelmed by decision-making. This also makes it easier and more realistic to swap developers between teams and helps new developers feel at ease.

When comparing AngularJS to ReactJS, the latter just provides the “View” in the MVC (Model View Controller), making it less structured and opinionated.

Component structure:

From a framework to a platform, AngularJS has come a long way. As a result, you may use its components with different frameworks with ease. Additional functionality can be implemented in the form of fully functional components or directives that enhance the functionality of an existing component.

Developing environment:

For AngularJS development, you can use your preferred environment. Although the majority of its developers utilise TypeScript, you can use Javascript or Dart instead. You can use either pure HTML or pre-processors like Jade to create templates.

Testing in AngularJS:

AngularJS was designed to make it simple to construct tests for apps, especially if you use modules, as the official documentation suggests. As a result, AngularJS has a significant testing advantage, which is even another reason to use it.

Disadvantages of using AngularJS

Here, are cons of using AngularJS

  • Steep learning curve
  • Scopes are challenging to debug Limited Routing
  • This framework sometimes becomes slow with pages embedding interactive components.
  • Third-party integration is complicated.

What is Angular Good for?

Angular is a frontend development framework that is notable for being a stand-alone solution for creating data-driven web apps. Because it was created by Google engineers, you can be confident in the code's stability and efficiency, which is backed up by a large community of specialists. Angular is notable for its model-view-controller capability, which improves the functionality of browser-based apps by lowering the amount of javascript code required to keep the project running.

Reasons for Choosing Angular

Rxjs and AngularCLI are built-in tools that make it easier to establish data channels and handle events independently. Using Angular, creating apps, adding files, and debugging a project is a breeze.

  • By running the components in parallel, it optimizes the developers' work and saves lines of code.
  • Improves overall performance.
  • Server-side rendering is quick, which helps views that don't have browser-side rendering.

Major Tech Companies using AngularJS

PayPal

PayPal is one of the world's largest and most widely utilized payment gateways. The PayPal checkout system, which includes critical functionality such as a payment review page and sites for adding credit cards, was built with Angular. As primary needs, these qualities carry a high level of security concerns as well as smooth functionality.

Upwork

Upwork is the most popular freelance site, with over 10 million freelancers using Angular. For highly functional platforms like Upwork, technologies like Angular are required to keep the capabilities running smoothly and to reflect changes in a fraction of a second.

Localytics

Localytics is a well-known technology that is utilized by companies like Microsoft, The New York Times, HBO, and others. It has used Angular to improve its features and establish a separate identity by utilizing the Angular UI suite and successfully lowering the amount of code required to keep the application running.

What is ReactJS Good for?

ReactJS is a free and open-source framework. It's used to manage the application's view layer, and developers choose it for creating reusable UI components. Changing the data without reloading the website is quick and scalable. ReactJS was originally used on Facebook and then later on Instagram's news feed. ReactJS is mostly used in large-scale applications to load data without refreshing the webpage.

Reasons for Choosing ReactJS:

  • Unlike Angular, ReactJS developers must integrate additional entities to obtain access to specific ReactJS functions and fully interactive functionality.
  • It contains Redux-like state containers for speedier creation of scalable apps, such as dynamic elements and renderer management.
  • Converting JSX to Javascript for better browser compatibility
  • Code bundlers, such as web pack, are required.
  • Using a URL routing library, such as ReactRouter.

Major Tech Companies using ReactJS

Netflix

ReactJS is used by Netflix, a world-class media streaming provider, primarily for low-performance devices. Netflix, for example, uses the ReactJS toolkit to boost runtime performance, modularization, and startup speed.

The New York Times

The New York Times has also created a whole new project to cover various celebrity appearances on the Oscar red carpet. The ReactJS framework was used to create the project, which allowed users to apply filters and select photographs of their choice. The ability to totally re-render has been highlighted as the most amazing feature of ReactJS.

Facebook

ReactJS is used by Facebook, however only in part. Their website uses React as a script that is integrated into the application code. The mobile app is also created with React Native, which is similar to React but is responsible for displaying native iOS and Android components rather than DOM elements.

It's worth noting that the ReactJS library was born on Facebook, which is why it's only natural for the app to use it. React Fiber, Facebook's entirely redesigned ReactJS, was just released as a beta.
