Usually, this question comes to mind, React vs Angular?

Yes, we should know also clearly….

Few major companies like WhatsApp, Instagram, Facebook, Netflix, Uber, etc. are using React. While companies like GM, Upwork, Google, Nike, etc. are using Angular.

React vs Angular

Let me give an overview of both things.

Angular is a framework build using TypeScript, developed and maintained by Google.

Whereas React is a Library, developed and maintained by Facebook. React library is used for building the UI (user interface) of an application.

There is a difference between a framework and a library.

Angular is a full-fledged MVC framework, by using which you can develop a complete MVC application. Whereas React is a JavaScript library used for managing the View in an MVC application.

One of the stands out the difference between React and Angular is DOM vs Virtual DOM.

React works with virtual DOM, whereas Angular worked with the real DOM.

The virtual DOM only looks at the differences between the previous and current HTML and changes the part that is required to be updated.

On the other side, since Angular is working on the real DOM, it will update the entire tree structure of HTML tags.

For small changes, there might not be a performance impact, but for a large number of changes, you will feel a performance impact.

Another important thing is React combines UI and JavaScript, which is known as JSX. React uses something called a component, which contains both the markup AND logic in the same file. It also uses an XML-like language that allows you to write markup directly in your JavaScript code.

On the other side, Angular uses HTML with its special Angular directives.

Both React and Angular based on Component based.

For example, a login box is a component that will have an Email Id, Password and a button. Components can be reused in different situations.

Another huge difference between Angular and React is, Angular supports two-way binding whereas React supports one-day binding.

What does it mean?

To way binding: If you change in the UI, then the corresponding model state will change. And also, if you change the model state then the corresponding UI element will get changed.

One way binding: In one way binding, if you change the model state, then the corresponding UI will be rendered. But the vice versa is not true. Means if you will change the UI, ten model state will not change.

React uses JavaScript whereas Angular uses TypeScript.

So users can take advantage of using JavaScript in react. For example, users do not need to declare a variable before using it.

But if you are using Angular then you need to little familiar with TypeScript syntax.

We already discussed TypeScript in our previous lectures.

To learn React, JavaScript knowledge is enough whereas to learn Angular has its own specific syntax.

Finally,

Both React and Angular are similar in terms of the component based architecture.

But Angular is a framework or a complete solution whereas react is a library. It only takes care of the rendering of the View and makes sure that the View is sync with the state of the application.

So if you are working with react, you need to work with other libraries too to implement the functionality. But in Angular, you have to depend on the APIs provided by Angular. Functionality can be like routing or calling APIs etc. In the case of React, you always have the freedom to choose the other libraries for M and V (from MVC).
