How To Install ReactJS on Window Step by Step 

what is ReactJS

React.js, also known as React, is a popular open-source JavaScript library for building user interfaces. Developed and maintained by Facebook, React is used for creating single-page applications and mobile applications.

React is based on the concept of building reusable UI components. A React component is a small piece of code that can be reused throughout your application to create the user interface. React uses a virtual DOM (Document Object Model) to efficiently update the UI without having to update the entire page.

React also provides a declarative approach to building user interfaces, which makes it easier to reason about the state of your application and the UI components that make up the user interface. This approach helps to reduce the amount of code you need to write, and it makes it easier to maintain and update your application over time.

React is widely used by developers because of its flexibility, performance, and ease of use. It is often used in conjunction with other libraries and frameworks such as Redux, React Native, and Next.js.

To install React.js on Windows, you need to follow these steps:

1. Install Node.js: React.js requires Node.js to run, so you need to install Node.js first. You can download the installer for your system from the official Node.js website: https://nodejs.org/en/download/

2. Open the Command Prompt: After installing Node.js, open the Command Prompt by pressing the Windows key + R and typing "cmd" in the Run box.

3. Install Create React App: In the Command Prompt, type the following command to install Create React App, which is a tool that helps you create React.js projects quickly:

   lua
   npm install -g create-react-app
   

4. Create a new React.js project: To create a new React.js project, navigate to the directory where you want to create the project using the cd command, then type the following command:

   lua
   npx create-react-app my-react-app
   

   This command will create a new React.js project in a directory called "my-react-app". You can replace "my-react-app" with any other name you want.

5. Start the development server: After creating the project, navigate to the project directory using the cd command, then start the development server by typing the following command:

   sql
   npm start
   

   This command will start the development server and open the React.js app in your default web browser.

That's it! You have successfully installed and set up React.js on your Windows system.
