React.js
React is the tool of preference for many web developers who build front-end web interfaces. It is an open-source, component-based front-end JavaScript library. It is used to create fast and interactive user interfaces for web and mobile applications. React makes it easy to create a dynamic application because it requires less coding and offers more functionality. Dubbed as the premium way to build rich experiences on the browser, many front-end developers have come to embrace it. React is a JavaScript library for building user interfaces. It’s just a library for rendering your views.
React environmental setup
For ReactJS environments, Node.js is required. To run the React application, Node.js should be installed on your PC.
Step 1: Install NodeJS.
Step 2: Create a directory for React.js App
Step 3: Go to the newly created ReactWorkspace directory location using a command.
(cd ReactWorkspace)
Step 4: Setting up the React Boilerplate.
(Npm install Create-react-app -g)

.-g is representing that the installation type is global.
Step 5: After successfully installing a global react environment. Create react demo app using the following command.
(create-react-app YourApplicationName)
Step 6: To start the development server, go inside your current directory and execute the below command.
(npm start)
React is the premier way to build big, fast Web apps with JavaScript. It has scaled very well on Facebook and Instagram. One of the many great parts of React is how it makes you think about apps as you build them. It has the potential to reuse components. It saves time for developers, as they don’t have to write various codes for the same features. Furthermore, if any changes are made in any particular part, it will not affect other parts of the application. React uses a special syntax called JSX instead of regular JavaScript for templating, which allows you to mix HTML with JavaScript. This is not a requirement; developers can still write in pure old JavaScript. HTML syntax is processed into JavaScript calls of React Framework.
You can also use React in existing apps. You can change a small part of your existing application by using React, and if that change works, then you can start converting your whole application into React.js. Facebook used the same approach.
Another interesting thing about React is how easy it is to grasp, particularly if you are already a pro at JavaScript. You can install React and be up and running in a few hours, getting straight to work building web applications. The documentation is clear, and there is a lot of it.
Conclusion
React is an excellent tool with which to create interactive applications for mobile, web, and other platforms.
React’s popularity and usage are increasing day by day for good reason. As a developer, coding in React makes you better at JavaScript, a language that holds nearly 90% of the web development share today.
