 Which one is better to learn in 2022, React.js or AngularJS

I'll assume you intended to write "Angular" rather than "AngularJS," which is a dated and no longer supported version.

Let's examine both React and Angular from above and contrast their similarities and differences. These lists must not go too much into the technical, otherwise, they would both be very lengthy.

First, the parallels

Both allow you to modify the rendered view whenever the application's state changes.

Both integrate nicely with a variety of third-party libraries that provide features that the core libraries for React or Angular do not.

Both allow for the creation of compact, specific, and reusable components.

I guess that's all. There are much more differences between the two projects than similarities:

React makes use of JSX, a JavaScript extension that enables you to build components inside JavaScript using a syntax akin to markup. JavaScript frequently contains elements that you might typically associate with HTML. Instead, Angular employs a templating approach where you specify the HTML for your component in a template that is tightly related to the component's code. Angular has its own syntax, which is utilized in the template, to implement binding between the two. It is feasible but uncommon to have both in a single file.

React is written in JavaScript, speaking of coding languages and syntax. On the other hand, Angular is written in Typescript. You can use Typescript with React if you want robust type-checking and type safety, but it's not recommended.

implemented into Angular in a way that is distinct from how it is built into React.

React has shifted away from class-based programming and toward functional programming in recent years. (This is even though their front page at reactjs.org is filled with class-based examples; it's commonly known in the developer community that they really need to improve their documentation.) Angular is obviously very focused on classes because it is created with Typescript, where classes have more functionality and are widely seen as superior to vanilla JavaScript classes.

And by far, the largest distinction is that React is a view library and not a framework. Routing, animations, REST/GraphQL clients, a state management system, and whatever else you add are all precisely that: To it was added. not by default present.

You gain certain benefits as a result.

To start, you are free to utilize any libraries you wish to do any task. Consider REST clients, for instance. For CRUD operations on a REST API, you could use Axios, fetch, request (please don't), or any number of other specialized libraries. React leaves decisions like those up to you because it doesn't aim to be anything more than a view library.

Second, adding React to an already-existing application is simple. In reality, a CDN can be used Without even needing NPM to install it, just load React and start using it. On the other hand, Angular is a complete framework. You commit to Angular and create the application as an Angular app, not by adding Angular to an already-existing application. Additionally, it includes utilities for all of that. It manages routing, backend communications, animation, views, state management, and a lot more that you can't even imagine.

There are benefits to this as well.

It eliminates a lot of the guessing, to start. You already know how to build components, manage routes, manage state, create pipes, and make REST requests from an Angular application. In short, you already know how to do pretty much everything. since everything is built-in.

Second, the all-in-one method makes maintaining an Angular project easier. Application updates were simple to complete. Due to the simultaneous management of all Angular libraries releases, you will never find yourself in dependency management hell.

Which one ought you to choose? I've noticed two parallel developments in recent years:

The king of startups is React. It's simple to include into existing software, and even inexperienced developers may quickly grasp its concepts. It takes extremely little time to go from scratch to having a functioning application, and if you already have one, integrating React is simple.

Angular is supreme in huge corporate settings. In those circumstances, developers are more likely to be seasoned, acquainted with Typescript (as many of them are native speakers of other type-safe languages), and inclined to value framework-imposed structure. Scalability is an additional consideration.

If you choose React, bear in mind that the combination of other libraries you choose to flesh it out will decide how effectively your application scales; after all, React isn't trying to be anything more than a view library. Do you anticipate 200 different users using this app each month? Or 200,000? Particularly if you decide against using an industrial-strength state management toolkit like Redux and develop your application as a single-page app without taking factors like lazy-loading into account, the decisions you make early on in a React application could come back to bite you. One of the reasons Angular is so well-liked in the business sector is that it takes care of all of that for you. Because it was built from the ground up to scale, it scales quite well. Many of the extra factors that you'll need to take into account when building a large, enterprise-ready application with React don't apply to Angular.

With all of that state, my advice on which to concentrate on will come down to whether you want to work for a huge corporation or a small-scale startup. If the former, master React and its ecosystem to the best of your ability. React might only be a view library on its own, but thanks to the ecosystem that has developed around it, it can be leveraged to create framework-like applications.

If the latter, Angular will make you a lot happier and more employable. If working with Typescript is what you prefer, go with Angular since it will provide you an advantage over it.

Happy studying in the future!
