Among the top JS libraries for creating front-end or GUI web apps is React JS, also known as React. React JS, sometimes referred simply as React, is a component-centric GUI development library supported by Facebook Design that has expanded by significant amounts in the past few years. React stands out from all the different front-end frameworks despite the availability of many others such as Vue and Angular. This is perhaps because it only concentrates on component-centric GUI creation and would not encroach into other domains. For instance, the comprehensive Angular framework comes with many features pre-installed, including Dependency Injection, Hooks, Routing, dealing with forms, HTTP requests, i18n presence, and a stong module structure with simple lazy-loading.
React is an excellent choice if you currently have libraries for doing those things or if you don't need them at all. However, understanding React can be challenging, primarily when you are new to web development.

Let’s go step-by-step about what needs to be done to master ReactJS. So, let’s get started, shall we?
Irrespective of the web development library or framework you wish to learn, you must be familiar with the fundamentals. By fundamentals, we mean HTML, CSS, and JS, which together form the three cornerstones of web development.
Given that it establishes the framework for a web page, it is among the primary components and the most crucial skills for anyone aspiring to become a web developer.
CSS is employed for the styling of web pages so that they seem appealing and is the second pillar of web development.
It makes no difference if you are a full-stack software engineer, a backend developer, or a front-end developer. Here is a summary of a few of the broader development skills you'll need to know in order to succeed in the realm of programming.
In 2022, you must be well conversant in Git. Understand how to import code from Github to your preferred IDE, try setting up some of the repositories on GitHub, and exchange your code with others.
You must be quite familiar with HTTP if you wish to work as a web developer. While we don't expect you to comprehend the specification, you must at the very least be acquainted with the GET, POST, PUT, and more standard HTTP request methods and how HTTP/HTTPS functions in general.
Even if a frontend programmer is not required to understand Linux or the terminal, we strongly advise you to become comfortable with it and set up your shell (bash, zsh, or csh), among other things.
However, while not necessarily essential to become a React developer, it is among the general programming abilities that must be acquired in order to qualify as a programming expert in initial time.
Similar to DSA, knowing design patterns is not necessary for becoming a React developer, however, you will benefit greatly from doing so. Design patterns are experimented answers to common issues that arise during the software development process. Understanding them can assist you in coming up with a plan that will work for you in the long run.
This goes without saying that to become a React developer, you must thoroughly understand React. The official React website is the best resource, but if you're just starting out, you might find it somewhat daunting. So, you may also take help from free courses available on the internet.
Invest a while to become acquainted with the tools you would use as a web developer, such as build tools, unit testing tools, debugging tools, etc., if you desire to become a competent React developer.
For beginners, understanding npm and webpack should be sufficient. It's not necessary to master all of these tools. You can investigate alternative technologies once you have a better knowledge of web development and the React Ecosystem.

Learning a little bit about styling will be beneficial for you if want to work as a front-end developer for React. Despite the fact that the Roadmap makes several references to things like CSS Architecture, CSS Frameworks, CSS Preprocessors, and CSS in JS.
We advise you to at least become familiar with Bootstrap, the most important CSS framework you will occasionally use.
Additionally, if you want to take it a step further, you may learn Material UI in addition to learning Bootstrap.
Another crucial aspect that a React developer should concentrate on is this one. The following are the concepts that you must learn and grasp:
React has several built-in type-checking capabilities, while you are not required to utilize them; mastering them can help you find errors earlier.
In addition to Type Checkers, learning Form Helps, which offers the best method for managing your form state in Redux, is a fantastic idea. You can also view Formik in addition to Redux Form.
The core of React's strong declarative programming paradigm is its routing components, which are a crucial component of every application.
A set of navigational components from React Router can be declaratively assembled with your application.
React Router works anywhere React is presenting, whether you require URLs that you can bookmark for your web app or a modular navigation system in React Native.
You could also explore Router 5, Redux-First Router, and React Router in addition to React-Router.
Nowadays, it is uncommon to create an isolated GUI. Rather, there is a higher likelihood that you will develop something that interacts with other applications using REST and GraphQL APIs.
Your job will be easier once you get your hands on these libraries. The following list of useful libraries is available to React developers:
Currently, this is a crucial skill for React developers that is sometimes disregarded, but if you wish to remain one step ahead of the pack, you must concentrate on understanding libraries that will aid in testing. Libraries for unit testing, integration testing, and end-to-end testing are also available here.
It is yet another crucial area for the development of the front end, which is widely employed. For countries in Europe like Spain, China, and Japan, you might have to support the regional GUI version.
The following technologies are recommended to learn:
Each of these libraries offers React components as well as an API for formatting dates, numbers, and texts, including managing translations and pluralization.
Top 30 frequently asked React JS Interview Questions !
Prior to actually discussing the library that allows server-side rendering with React, let's address the question of what the distinction between client-side rendering and server-side rendering is.
As opposed to server-side rendering, which renders React components on the server and then sends the finished HTML content to the client or browser.
It offers Server rendering, which is something that rails/webpacker do not and is frequently used for indexing by SEO crawlers and UX performance.
The following libraries should be learned, according to the Roadmap:
Additionally, there are React-based desktop GUI frameworks like React Native Windows that let you create native UWP and WPF apps.
There are frameworks like React 360 that let you create engaging 360 and VR interactions with React if you're interested in developing applications dependent on virtual reality.
Following are some of the prerequisites we suggest you get your hands on:
CSS and HTML
The cornerstone for all front-end developers is HTML and CSS. Therefore, ensure that you are familiar with HTML and CSS coding before beginning to master ReactJS.
Node Package Manager
Bootstrap is a front-end UI framework that offers a robust grid (container, row, and col) architecture and pre-made UI components, making it simple for ReactJS developers to quickly design stunning user interfaces.
Git and CLI
Git (version control), which enables developers to save their projects on GitHub, Bitbucket, and GitLab, is another prerequisite for programmers (Code hosting platform). It makes it possible for programmers to cooperate and work together in addition to tracking and hosting different project file versions.

You will break down things that need to be learned into phases. These things are the ones that you must know to have a career in ReactJS.
After learning React, you can opt to master more tools. Tools that let developers operate on the server side, or back end, of websites, are included in this. These tools, including Node. js, Express. js, and MongoDB, are introduced in this post along with instructions on how to get started learning them.
Because of its virtual DOM implementation and rendering improvements, React is stronger than Angular. React's version migration is also very simple; unlike Angular, you don't have to install updates one at a time. Furthermore, React gives developers access to a vast array of pre-existing solutions.
