React JS vs Angular: Which Framework Should you Choose (and Why)

React JS vs Angular. Choosing the right front-end framework for your project is very important. It can either make or break your project down. It can affect your project’s deadline, scalability, durability, and code maintainability.

JavaScript is one of the fastest-growing technology in the world of software development. Ever since its inception in 1995, there have been more new frameworks introduced in the past five years than ever.

React JS and Angular JS are the most popular front-end frameworks in the world. According to the State of JS, 64.8% of the developers have used React JS and are willing to use it in the future. Whereas, 23.9% of the developers have used Angular JS and are eager to use it in the future.

Both frameworks have their bright side and dark sides. This article will help you to determine which framework will suit best for your project or application.

React JS vs Angular

If we compare Angular JS vs React JS, then Angular is a framework that offers multiple out of the box designs and frameworks. On the other hand, React JS comprises several components that are used as building blocks in various applications.

An introduction to React JS

React is a framework that is owned, developed, and maintained by Facebook and a community of millions of programmers and front-end developers.

React has been in this game for around six years now. Popular apps like Facebook, Instagram, Airbnb, WhatsApp, Netflix, etc. use React as their main front-end framework.

An introduction to Angular JS

Angular JS in an opensource framework introduced by Google. Angular JS has been around eight years in the industry. There are 600,000+ applications built using Angular.

Since it is an older framework than React, Angular JS uses an extended version of HTML to create templates. Unlike React, it offers dependency injection.

Benefits of Angular JS

  • Community collaboration is one of the primary reasons for Angular to be a popular framework. Designers and developers constantly contribute to the community, which is extremely helpful.
  • With Angular JS development, you can create browser-independent web applications.
  • It is consistent, contains many ready-to-use tools, ng components, and is robust and mature compared to React JS.
    Among all its features, two-way data binding is a classic one. A developer does not have to put extra efforts to sync data in view and model.
  • TypeScript offers improved JS super-set that provides optional static type checking, object-oriented programming patterns, and high-performing typing features.
  • Because of the component-based architecture, the reusability of a component is higher in Angular. Therefore, it increases code testability and maintainability.

Benefits of React JS

  • JSX is one of the most prominent features of React JS. It enables the usage of HTML tag syntax and HTML quotes for the rendering of subcomponents.
  • Instantaneous rendering is one of those features that give React an edge over Angular. It does that by reducing the amount of DOM operations.
  • Since React is JS-based, it is much more robust compared to Angular, which is HTML-based.
  • React is a great choice for scalable businesses because using it, you can scale your website along with your business.
    React JS provides great flexibility and responsiveness.
  • Angular only supports web development, whereas React supports both web and native-like mobile app development.

An In-depth Comparison

Implementation

While comparing React JS vs Angular, Angular offers a large number of native features and options. Starting a project in Angular JS is easier compared to React.

In React, one needs to add external component libraries to get the same number of features. Routing will become a necessary element to force unidirectional flows, set up tests, manage dependencies, call APIs, and more.

Data Binding

Angular JS uses two-way data binding, which connects the DOM values to the model data. It means that whenever a developer passes a new value in a particular field, it will reflect in both view and model. This two-way data binding can reduce the performance of an application.

React JS uses one-way data binding, which offers singular behavior of an application. Since singularity is getting separated from the classes by implementing dependencies, the risk of errors is getting reduced.

Performance

Angular’s MVVM architecture significantly reduces the page loading time. Its asynchronous mode of communication reduces the number of entrances to the server.

React’s Virtual DOM increases the speed of navigation within the website, which further reduces the website loading time. Therefore, applications built in React are faster than the ones made in Angular.

Dependency Injection

It is a software design pattern that helps in making components reusable, testable, and maintainable. Angular automatically gets the appropriate objects with parameters.

Whereas, the dependency injection is missing in React. Here, it is done by the inclusion of modules, such as RequireJS, Browserify, and more.

Directives and Templates

Angular provides default directives to work on DOM. Moreover, one can also create his/her directives. It makes the binding of DOM elements with Angular apps easier.

React requires the template logic to be written in the template itself. It does not offer any division into templates and directives. React will reinterpret all the UI templates whenever an event occurs.

Scalability

Angular is easier to scale because of its powerful CLI and intuitive design. Comparing Angular JS vs React JS, React is slightly less scalable compared to Angular but certainly more scalable compared to other frameworks such as Vue JS.

Conclusion

When to opt Angular JS over React JS?

If you are starting a project from ground zero and looking for a holistic framework, which also helps you to start the project quickly, then Angular is the right choice for you.

Moreover, if you’re looking for a well-maintained and robust front-end framework, then Angular is the right choice for you.

When to use React JS over Angular Js?

If you’re looking for a framework that scales your application as you grow your business, then React is the right choice for you.

If you don’t mind a slower start and have a requirement to update content on the website quite frequently, then React JS development is the right choice for you.
