⚛️ React Basics (Components, Props, State)

Now you move from simple websites → modern frontend apps.

React is used in real companies like Netflix, Facebook, Airbnb.

⚛️ What is React 
React is a JavaScript library for building UI. 
👉 Developed by Facebook 
👉 Used to build fast interactive apps 
👉 Component-based architecture 
Simple meaning 
• Break UI into small reusable pieces
Example 
• Navbar → component
• Card → component
• Button → component

🧱 Why React is Used 
Without React 
• DOM updates become complex
• Code becomes messy
React solves: 
✅ Faster UI updates (Virtual DOM) 
✅ Reusable components 
✅ Clean structure 
✅ Easy state management 

🧩 Core Concept 1: Components 
❓ What is a component 
A component is a reusable UI block. 
Think like LEGO blocks. 

✍️ Simple React Component 

function Welcome() {
    return <h1>Hello User</h1>;
}

Use component 

<Welcome />

📦 Types of Components 
🔹 Functional Components (Most Used) 

function Header() {
    return <h1>My Website</h1>;
}

 
🔹 Class Components (Old) 
Less used today. 

✅ Why components matter 
• Reusable code
• Easy maintenance
• Clean structure

📤 Core Concept 2: Props (Passing Data) 
❓ What are props 
Props = data passed to components. 
Parent → Child communication. 

Example 

function Welcome(props) {
    return <h1>Hello {props.name}</h1>;
}

Use 

<Welcome name="Deepak" />

Output 👉 Hello Deepak 

🧠 Props Rules 
• Read-only
• Cannot modify inside component
• Used for customization

🔄 Core Concept 3: State (Dynamic Data) 
❓ What is state 
State stores changing data inside component. 
If state changes → UI updates automatically. 

Example using useState 

import { useState } from "react";
function Counter() {
    const [count, setCount] = useState(0);
    return (
        <div>
            <p>{count}</p>
            <button onClick={() => setCount(count + 1)}>
                Increase
            </button>
        </div>
    );
}

🧠 How state works 
• count → current value
• setCount() → update value
• UI re-renders automatically
This is React’s biggest power. 

⚖️ Props vs State (Important Interview Question) 
| Props | State |
|-------|-------|
| Passed from parent | Managed inside component |
| Read-only | Can change |
| External data | Internal data |

⚠️ Common Beginner Mistakes 
• Modifying props
• Forgetting import of useState
• Confusing props and state
• Not using components properly

🧪 Mini Practice Task 
• Create a component that shows your name
• Pass name using props
• Create counter using state
• Add button to increase count

✅ Mini Practice Task – Solution

🟦 1️⃣ Create a component that shows your name 

function MyName() {
    return <h2>My name is Deepak</h2>;
}
export default MyName;

✔ Simple reusable component 
✔ Displays static text 

📤 2️⃣ Pass name using props 

function Welcome(props) {
    return <h2>Hello {props.name}</h2>;
}
export default Welcome;

Use inside App.js 

<Welcome name="Deepak" />

✔ Parent sends data 
✔ Component displays dynamic value 

🔄 3️⃣ Create counter using state 

import { useState } from "react";
function Counter() {
    const [count, setCount] = useState(0);
    return <h2>Count: {count}</h2>;
}
export default Counter;

✔ State stores changing value 
✔ UI updates automatically 

➕ 4️⃣ Add button to increase count 

import { useState } from "react";
function Counter() {
    const [count, setCount] = useState(0);
    return (
        <div>
            <h2>Count: {count}</h2>
            <button onClick={() => setCount(count + 1)}>
                Increase
            </button>
        </div>
    );
}
export default Counter;

✔ Click → state updates → UI re-renders 

🧩 How to use everything in App.js

import MyName from "./MyName";
import Welcome from "./Welcome";
import Counter from "./Counter";

function App() {
    return (
        <div>
            <MyName />
            <Welcome name="Deepak" />
            <Counter />
        </div>
    );
}
export default App;

⚛️ React Routing (Complete Overview)

React Routing allows a React app to display different components based on the URL without reloading the page.

Since React apps are Single Page Applications (SPAs), routing is handled on the client side using React Router.

It makes your app feel fast and smooth because only the needed component updates — not the whole page.


🔑 Main Components in React Router

1️⃣ BrowserRouter

Wraps your entire app and enables routing using the browser’s history API.

import { BrowserRouter } from "react-router-dom";

<BrowserRouter>
<App />
</BrowserRouter>


2️⃣ Routes

A container that holds all your route definitions.

<Routes>
{/* Routes go here */}
</Routes>


3️⃣ Route

Defines which component should render for a specific path.

<Route path="/about" element={<About />} />

path → URL path

element → Component to display


4️⃣ Link

Used to navigate between pages without refreshing.

import { Link } from "react-router-dom";

<Link to="/about">About</Link>

It replaces the normal <a> tag because <a> reloads the page, but Link keeps the SPA behavior.

Custom Hooks in React

A custom hook is a JavaScript function that:

Starts with use

Uses built-in hooks like useState or useEffect
Reuses stateful logic between components


👉 Custom hooks reuse logic, not UI.

Why Use Custom Hooks?

Instead of repeating logic (fetching data, forms, pagination, auth), you extract it into one reusable function.

This keeps components:

Cleaner,Smaller,Easier to maintain

Simple Real Example

import { useState, useEffect } from "react";

function useFetch(url) {
const [data, setData] = useState(null);

useEffect(() => {
fetch(url)
.then(res => res.json())
.then(data => setData(data));
}, [url]);

return data;
}

Use it inside a component:

const data = useFetch("https://api.example.com/data");

Now the fetching logic is reusable anywhere.

Key Idea

Custom Hooks = Reusable stateful logic

They: Don’t return JSX, Don’t render UI

Only manage logic

I’ve realized that learning without practice doesn’t really benefit me. So instead of just reading and watching tutorials, I decided to build something.

I’m starting a simple CryptoTrack website to track cryptocurrency prices, and I’ll make it have multiple pages so I can properly practice routing in React.

Time to turn learning into building 💻

@futurefullstack

was just reading some news today and it honestly blew my mind.

we mostly just use AI to help us code or write emails, but it turns out the US military has been using tools like Claude for actual combat planning. there are even reports they used AI during the recent airstrikes on Iran.

the crazy part is the drama behind it. Anthropic (the company behind Claude) actually pushed back. they drew a hard line saying they wouldn't allow their AI to be used for fully autonomous weapons. because of that, the pentagon basically cut ties with them and went looking for other companies (like OpenAI) who would agree to their terms.

it’s just wild to think about. AI isn't just our little coding assistant anymore.. it’s literally becoming the brain behind global warfare.

kind of a scary reality check today. what do you guys think about AI being used for stuff like this?

Today I learned about TanStack Query and how it simplifies data fetching and caching in React. It’s interesting to see how it removes a lot of the complexity we usually deal with when using useEffect and manual state management.

I also tried to refactor my CryptoTracker project using what I learned. The refactoring went pretty well and the structure feels better now.

Unfortunately, there’s one bug I couldn’t debug today 😅. I’ll revisit it tomorrow with a fresh mind.

That’s it for today.
Good night everyone 🌙
