This article mainly introduces "what are the differences between React and Angular". In daily operation, I believe many people have doubts about the differences between React and Angular. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "what are the differences between React and Angular?" Next, please follow the editor to study!

What is React?

React is a UI library developed and open source by Facebook. What I want to emphasize is that it is the library here. I will explain why this is important later.

React is by far the most popular UI library, supporting thousands of websites. React uses JavaScript as the main language and can run on many platforms, including Web,Android,iOS and even VR.

What is Angular?

Angular is a front-end framework developed and open source by Google. Right away, you'll find that they are fundamentally different: React is a library and Angular is a framework. In the previous section, I will explain the difference between the two terms.

Angular uses TypeScript as its main language and can also run on a variety of platforms. The architecture of Angular adopts the MVC (Model-View-Controller) pattern, which is considered to be one of the industry standards. So, what are the similarities between React and Angular?

How similar are they?

First, both React and Angular produce the same deliverables: a front-end application, whether it's a website, an application, or something in between. Both use JavaScript in the background and take full advantage of NPM (Node package Manager), which makes it easy to share duplicated code.

Community

There are huge communities behind both products. Because React and Angular are open source, many companies rely on them and try to keep them running and up-to-date, so you feel relatively secure when using them. Due to incomplete documentation, lack of help on Stack Overflow, or the availability of third-party libraries, you are unlikely to encounter many problems.

Architecture

Both solutions provide an architecture similar to MVC, although there are some misunderstandings (as I will describe in the previous section). In addition, both Angular and React allow you to develop using TypeScript, but only React supports pure JavaScript. Finally, both are component-based, which is very consistent with the rest of the UI framework (Vue,Flutter, etc.).

What's the difference between them?

Oh, boy. We have a lot of points here-I think that's why you read this article. So let's get started.

Library and framework

As mentioned earlier, React is a library and Angular is a framework. In short, libraries can solve problems, while frameworks can solve problems. In most cases, the framework consists of libraries. What does this actually mean: React is very light, fast, and easy to learn, but it doesn't do anything on its own (except for drawing some buttons). You will need third-party libraries for routing, API connections, state management, etc. Angular, on the other hand, has this library and is much more built-in. Although Angular is difficult to learn, it provides you with good features, such as routing, form generation, dependency injection, and so on. In MVC, React is only part of it, but Angular is the whole.

Regular DOM and Virtual DOM

Angular and React use slightly different methods when rendering content on the screen. Angular behaves as you would expect: each time it renders again, it builds a new DOM from scratch and replaces it in the browser. React, on the other hand, tries to reuse as much as possible. It calculates the minimum set of operations required to bring the browser's DOM to React's internal virtual DOM and execute them. This will lead to a huge performance improvement, which will become more obvious once the concurrency mode is introduced.

Expandability

This is one of Angular's strengths. Because the architecture of the Angular implementation is more complex, it is easier to scale. In React, too much is on the shoulders of developers, and it's much easier to screw up. However, you won't notice it until the code base is large enough. Of course, this situation can be mitigated by applying the "clean architecture" principle, but you need to be aware of this.

Mobile development

React used to be the clear winner for the division, but it is not so obvious now. React Native allows you to write native applications using React, and NativeScript allows you to write native applications using Angular and Vue. Both provide comparative performance and feature sets. The difference lies in platform access. If you want to access some native API methods in React Native, you must write a bridge using Kotlin or Swift. On native scripts, you can access native methods directly from JS code. On the other hand, React Native has a larger community, which is a priceless asset. However, if performance is a top priority, Flutter should be considered.

At this point, the study on "what is the difference between React and Angular" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
