What is react JS? 

Introduction:

Hello friends, welcome to our new post!
Let’s understand what React is. In today’s era, we all know websites like Myntra, Facebook, Instagram, and Netflix — all of these websites are built using React JS.

But why React?

Because React JS is a JavaScript library used to build user interfaces (UIs) — especially for web applications. It helps developers create fast, dynamic, and interactive websites using reusable blocks called components.

React was created by Facebook in 2013 and is now maintained by Meta, along with a huge community of developers.

Here are some reasons why developers love React:

  • Simplified and Declarative Syntax
    React makes writing code straightforward and readable.

  • Uses Virtual DOM for Performance Optimization
    React updates only the necessary parts of the page, making it super fast.

  • Flexible
    Works for small projects as well as large-scale applications.

  • Active Community
    Thousands of developers contribute daily, making learning easier.

  • Extensive Resources Available
    Official documentation, courses, tutorials, and open-source libraries simplify development.

  • Seamless TypeScript Integration
    Easily integrates with TypeScript for strongly typed development.

  • Rich Ecosystem & Tooling
    Works with Redux, Next.js, React Router, and many other powerful tools.

How to get started with react?
before you continue you should have a basic understanding of the following:
  • HTML
  • CSS
  • JavaScript

Once you’re ready, the easiest way to start is using this command:
  • Install Node.js & npm
  • Install VS Code
  • Run npx create-react-app my-app to create a new React project
  • Open folder in VS Code: cd my-app
  • Run React app: npm start

JSX makes our code: Simple to understand  Easy to build components Readable and short  JSX is Like Writing Recipes Let’s assume you're a chef  JSX is your easy-to-read recipe card : “1 bowl rice, 2 spoon...
