React

Introduction

React is a popular JavaScript library for building user interfaces. It was developed by Facebook and is commonly used for creating web applications with dynamic, interactive user interfaces. React allows developers to build reusable UI components and manage the state of their applications efficiently.

Key features and concepts of React include

  • Component-Based Architecture: React encourages developers to break their user interfaces into small, reusable components. Each component manages its own state and can be composed to build complex user interfaces.

  • Virtual DOM (Document Object Model): React uses a virtual representation of the DOM to optimize updates and minimize actual DOM manipulation. This results in improved performance and a smoother user experience.

To install React on both Windows and macOS, you'll need to set up a development environment that includes Node.js and npm (Node Package Manager).

NPM is the package manager that comes with Node.js and is used to install and manage libraries and dependencies, including React.

Prerequisites for local development

Node.js and npm: Ensure you have Node.js and npm installed on your system. You can download them from the official website:

https://nodejs.org/

Installing Node.js also installs npm. You can verify the installation by opening a terminal (Command Prompt on Windows or Terminal on macOS) and running the following commands to check the installed versions:

    node -v
    npm -v

Text Editor or IDE: You'll need a code editor or integrated development environment (IDE) to write React code. Popular choices include Visual Studio Code, IntelliJ Idea, or WebStorm. We recommend to use VS Code or IntelliJ Idea.
