✅ React.js Essentials ⚛️🔥 React.js is a JavaScript library for building user interfaces, especially single-page apps. Created by Meta, it focuses on components, speed, and interactivity. 1️⃣ What is React? React lets you build reusable UI components and update the DOM efficiently using a virtual DOM. Why Use React? • Reusable components • Faster performance with virtual DOM • Great for building SPAs (Single Page Applications) • Strong community and ecosystem 2️⃣ Key Concepts 📦 Components – Reusable, independent pieces of UI.

function Welcome() {
  return <h1>Hello, React!</h1>;
}

🧠 Props – Pass data to components

function Greet(props) {
  return <h2>Hello, {props.name}!</h2>;
}
<Greet name="Riya" />

💡 State – Store and manage data in a component

import { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);
  return (
    <>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>Add</button>
    </>
  );
}

3️⃣ Hooks useState – Manage local state useEffect – Run side effects (like API calls, DOM updates)

import { useEffect } from 'react';

useEffect(() => {
  console.log("Component mounted");
}, []);

4️⃣ JSX JSX lets you write HTML inside JS.

const element = <h1>Hello World</h1>;

5️⃣ Conditional Rendering

{isLoggedIn ? <Dashboard /> : <Login />}

6️⃣ Lists and Keys

const items = ["Apple", "Banana"];
items.map((item, index) => <li key={index}>{item}</li>);

7️⃣ Event Handling

<button onClick={handleClick}>Click Me</button>

8️⃣ Form Handling

<input value={name} onChange={(e) => setName(e.target.value)} />

9️⃣ React Router (Bonus) To handle multiple pages

npm install react-router-dom

import { BrowserRouter, Route, Routes } from 'react-router-dom';

🛠 Practice Tasks ✅ Build a counter ✅ Make a TODO app using state ✅ Fetch and display API data ✅ Try routing between 2 pages 💬 Tap ❤️ for more
