Should I use Angular or React to build my web or mobile app? It’s a question both novices and veterans alike will eventually have to tackle if they’re to keep up with the ever-evolving world of front-end web development. In one corner, you have Angular—a comprehensive application design framework and development platform developed and maintained by Google.

Gmail, YouTube TV, and Udacity all use Angular in their technology stacks.

What is React?

In the other corner, you have React—a performant UI (user interface) library developed and maintained by Facebook. Instagram, Facebook, and Netflix are some examples of apps built with React.

While there is indeed some overlap in function, the two technologies are as different as Google and Facebook themselves. Angular is a framework, while React is a library.

Angular vs. React.js: Tech Side

  • Angular developers prefer two-way data binding while React developers prefer unidirectional data flow. Read on to explore some of the key differences between the two technologies and determine which one is right for your project.
  • While it would be simple to dismiss the difference between Angular and React as one of frameworks and libraries, the truth is that most developers using React as a view library will also use other libraries in the React ecosystem to turn it into a complete framework.
  • This is why React is often grouped with other JavaScript frameworks such as Angular and Vue.js.
  • To truly understand the differences, it’s important to dive into the details. Angular is a full-fledged JavaScript framework written in TypeScript (a superset of JavaScript).
  • Initially released by Google in 2016 as Angular 2, it’s a complete rewrite of the old reigning king of JavaScript development frameworks: AngularJS.


  • The new Angular was designed to compete with React by embracing components while retaining the dependency injection (DI) and two-way data binding features Angular developers had come to love.
  • Standard features of Angular include:.
  • Dependency injection.
  • Two-way data binding. Routing with @angular/router.
  • Forms with @angular/forms. Component CSS encapsulation.
  • React (also known as React.js or ReactJS) was initially released in 2013 as an open-source JavaScript library for rendering views.
  • Instead of providing the model, view, and controller, like the old AngularJS, React is only the view.
  • React popularized the components-based architecture for web and mobile development, allowing developers to choose how they wanted to manage state with other libraries and frameworks.

React.js vs. Angular: Brief Overview

  • React preferred to handle state management with libraries that encouraged working with immutable data and one-way data binding to achieve unidirectional data flow.
  • Standard features of React include:.
  • Virtual DOM (Document Object Model).
  • Functional components.
  • Basic state management with setState and Context API.
  • Here’s a summary of the main differences between Angular and React:.
  • The main idea behind componentization in web development is to isolate front-end features into encapsulated components that are easier to reuse, test, secure, deploy, and modify without breaking the rest of the app.
  • Not only does componentization help with separation of concerns for splitting projects across multiple developers, it also makes the application easier to scale with changing user demands and markets.
  • React started the components-based web development revolution in 2013 when it demonstrated you could apply a components-based architecture at scale to websites and mobile apps.
  • Components gave the library a competitive advantage over AngularJS, which was still following the traditional MVC (model, view, controller) approach to web development.

Angular vs. React: Critical Pros and Cons

The difference between performance was hard to overlook, which prompted Google to perform a complete rework of AngularJS into Angular 2.

  • Today, both React and Angular are components-based.
  • Logic is encapsulated within UI components for common front-end features such as sign-in forms, text inputs, and buttons.
  • These UI components can be easily repurposed with different data and styles for other pages and apps.
  • Where they differ is in how they achieve componentization.

Which Companies Use Which One?

In the Angular world, components are decorators (@component), functions that allow a service, directive, or filter to be modified prior to usage.

  • They allow us to tell if a class is a module or component and pull the necessary metadata together to determine how a view should be rendered.
  • In React, components are actually JSX files that contain both JavaScript and HTML templating in a single file.
  • These components can be class based or pure functions depending on the needs of the developer.
  • And props can be passed through components in a unidirectional fashion.

Angular vs. React: Side-by-Side Comparison

  • Data binding is the mechanism connecting the data model to the view or UI.
  • Much has been written on the debate between the merits of two-way data binding (Angular) and one-way data binding (React).
  • In reality, you can do both with Angular and React. The key differentiator is that two-way data binding is included within Angular by default, whereas with React it’s about selecting the right state management library.


  • In one-way data binding, data flows in one direction from the model to the view.
  • The advantage of unidirectional data flow is that it becomes easier to manage state across your application.
  • You know that any changes made by the state in a particular component can only affect the components below it.
  • Siblings and parent components will remain isolated from any changes to the state of that component.

So which is better—Angular or React?

TypeReact is a JavaScript library, and it is much older compared with Angular.Angular is a complete framework.
Use of librariesReact js can be packaged with other programming libraries.Angular is a complete solution in itself.
Learning curveIt is easier to grasp compared Angular. However, it is difficult to learn when augmented with Redux.Learning Angular is not easy for beginners. Thus, it requires lots of training.
Community supportWhen it comes to community support React doesn’t offer much.It has a viable and dependable community support system
Installation timeReact takes longer to set up. But, it is really fast for delivering projects and building apps.Angular is easy to set up but may lead to an increase in coding time which also results in delayed project deliveries.
Best featureIt gives you the freedom to choose the tools, architecture, and libraries, for developing an app.It offers a limited amount of freedom and flexibility.
Data bindingReact language uses one-way data binding, which means that the Ul elements can’t be changed without updating the corresponding model state.Angular, on the other hand, uses the two-way data binding method. It helps you to ensure that the model state automatically changes when any change is made.
Testing & DebuggingIt requires a set of tools to perform different types of testing.The testing and debugging for a complete project is possible with a single tool.
DocumentationAlthough it is also undergoing regular updates, the documentation is relatively faster.Due to the ongoing development process, the documentation is slower.
UpdatesUpdates in React are simple because scripts help in the migration.It plans updates every six months, which gives some time to make needed changes for migration.

When to use which framework – Angular vs React

In two-way data binding, data flows in both directions between the model and the view.

  • Any change that updates the view will also update the model and vice versa.
  • The primary advantage to two-way data binding is that the updates are instantaneous and make data management easier for the developer (you know your view and model are in sync).
  • This convenience comes at a performance cost however—the number of watchers and watched elements needed to support two-way data binding will naturally scale as applications grow in complexity and size.
  • While React was the clear winner over AngularJS, with the release of Angular 2 in 2016, the two front-end technologies have been neck and neck in terms of performance benchmarks.
  • Performance is comparable for most general metrics.
  • Depending on the version or test, sometimes either React or Angular will come out ahead.
  • Angular tends to perform better overall for task-based benchmark tests.
  • React does seem to show an advantage when you look at overall site load times.

Which Is Better: Angular or React?

This makes sense because React uses a virtual DOM to efficiently load specific parts of a webpage while Angular manipulates the DOM directly (which is resource intensive).

  • This performance edge is most visible when a page has to update many views at once such as image and video galleries found in social media apps like Facebook and Instagram.
  • Bottom line, performance should not be the main reason for choosing between React or Angular.
  • Both are top-tier front-end JavaScript technologies that can be used to create performant websites and mobile apps.
  • Specific architecture design choices will matter more if performance is a concern.
  • React is likely the easiest to learn among the JavaScript frameworks because all you need to know to use React is HTML and JavaScript.

React Vs Angular Comparision – Tabular Difference Overview

Once you get used to JSX files, it’s easier to build your app as encapsulated components and add on libraries as needed to accommodate missing features as they come up during development.

  • To use Angular you would need to learn TypeScript and the Angular-specific commands and patterns associated with the framework.
  • On the other hand, some would argue that the “batteries included” approach of a full framework like Angular, coupled with the excellent Angular CLI, uniform documentation, and less fragmented ecosystem means Angular is easier to learn.

Angular vs. React: What’s the difference?

At the end of the day, personal preference and experience will largely impact which is easier for a developer to pick up.

  • Both JavaScript frameworks have large thriving communities on GitHub and Stack Overflow.
  • It’s worth noting that because React by itself is just a library, it is of course easier to pick up as a new technology as there is less to learn.
  • Developers looking to build apps for mobile with Angular or React have two options:.
  • Create a hybrid app via integration with a framework such as Ionic.
  • You create an Angular or React app that’s hosted in a native WebView Component (wrapper).
  • Create a compiled app via integration with a framework such as React Native or NativeScript (for Angular).
  • You create an app with UI components that compile code into native device language.

What is Angular?

The trade-off between hybrid apps and compiled apps is programmer productivity and performance. The hybrid app is easier to build because you are essentially creating a web app and porting it to mobile.

The compiled app boasts near native performance, but requires you to modify your web app code to fit the compiled app framework.
