4οΈβ£ Basic Server Example:
const http = require('http');
http.createServer((req, res) => {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello, Node.js!');
}).listen(3000); // Server listening on port 3000
5οΈβ£ npm (Node Package Manager):

6οΈβ£ Express.js (Popular Framework):
const express = require('express');
const app = express();
app.get('/', (req, res) => res.send('Hello World!'));
app.listen(3000, () => console.log('Server running on port 3000'));
7οΈβ£ Working with JSON & APIs:
app.use(express.json()); // Middleware to parse JSON body
app.post('/data', (req, res) => {
console.log(req.body); // Access JSON data from request body
res.send('Received!');
});
8οΈβ£ File System Module (fs):
const fs = require('fs');
fs.readFile('file.txt', 'utf8', (err, data) => {
if (err) throw err;
console.log(data); // Content of file.txt
});
9οΈβ£ Middleware in Express:
Functions that run before reaching the route handler.
app.use((req, res, next) => {
console.log('Request received at:', new Date());
next(); // Pass control to the next middleware/route handler
});
π Real-World Use Cases:
- REST APIs π

let count = 0;
return function inner() {
count++;
console.log(count);
};
}
const counter = outer();
counter(); // 1
counter(); // 2
2οΈβ£ Promises & Async/Await
Promises handle async operations; async/await makes them read like sync code. Essential for APIs, timers, and non-blocking I/O.
// Promise chain
fetch(url).then(res => res.json()).then(data => console.log(data)).catch(err => console.error(err));
// Async/Await (cleaner)
async function getData() {
try {
const res = await fetch(url);
const data = await res.json();
console.log(data);
} catch (err) {
console.error(err);
}
}
3οΈβ£ Hoisting
Declarations (var, function) are moved to the top of their scope during compilation, but initializations stay put. let/const are block-hoisted but in a "temporal dead zone."
console.log(x); // undefined (hoisted, but not initialized)
var x = 5;
console.log(y); // ReferenceError (temporal dead zone)
let y = 10;
4οΈβ£ The Event Loop
JS is single-threaded; the event loop processes the call stack, then microtasks (Promises), then macrotasks (setTimeout). Explains why async code doesn't block.
5οΈβ£ this Keyword
Dynamic binding: refers to the object calling the method. Changes with call site, new, or explicit binding.
const obj = {
name: "Sam",
greet() {
console.log(`Hi, I'm ${this.name}`);
},
};
obj.greet(); // "Hi, I'm Sam"
// In arrow function, this is lexical
const arrowGreet = () => console.log(this.name); // undefined in global
6οΈβ£ Spread & Rest Operators
Spread (...) expands iterables; rest collects arguments into arrays.
const nums = [1, 2, 3];
const more = [...nums, 4]; // [1, 2, 3, 4]
function sum(...args) {
return args.reduce((a, b) => a + b, 0);
}
sum(1, 2, 3); // 6
7οΈβ£ Destructuring
Extract values from arrays/objects into variables.
const person = { name: "John", age: 30 };
const { name, age } = person; // name = "John", age = 30
const arr = [1, 2, 3];
const [first, second] = arr; // first = 1, second = 2
8οΈβ£ Call, Apply, Bind
Explicitly set 'this' context. Call/apply invoke immediately; bind returns a new function.
function greet() {
console.log(`Hi, I'm ${this.name}`);
}
greet.call({ name: "Tom" }); // "Hi, I'm Tom"
const boundGreet = greet.bind({ name: "Alice" });
boundGreet(); // "Hi, I'm Alice"
9οΈβ£ IIFE (Immediately Invoked Function Expression)
Self-executing function to create private scope, avoiding globals.
(function() {
console.log("Runs immediately");
let privateVar = "hidden";
})();
π Modules (import/export)
ES6 modules for code organization and dependency management.
// math.js
export const add = (a, b) => a + b;
export default function multiply(a, b) { return a * b; }
// main.js
import multiply, { add } from './math.js';
console.log(add(2, 3)); // 5

π¬ Tap β€οΈ if you're learning something new!let for reassignable variables, const for constants (avoid var due to scoping issues).
let name = "Alex";
const age = 25;
Data Types: string, number, boolean, object, array, null, undefined.
2οΈβ£ Functions
Reusable blocks of code.
function greet(user) {
return `Hello, ${user}`;
}
Or use arrow functions for concise syntax:
const greet = (user) => `Hello, ${user}`;
3οΈβ£ Conditionals
if (age > 18) {
console.log("Adult");
} else {
console.log("Minor");
}
4οΈβ£ Loops
for (let i = 0; i < 5; i++) {
console.log(i);
}
5οΈβ£ Arrays & Objects
let fruits = ["apple", "banana"];
let person = { name: "John", age: 30 };
6οΈβ£ DOM Manipulation
document.getElementById("demo").textContent = "Updated!";
7οΈβ£ Event Listeners
button.addEventListener("click", () => alert("Clicked!"));
8οΈβ£ Fetch API (Async)
fetch("https://api.example.com").then(res => res.json()).then(data => console.log(data));
9οΈβ£ ES6 Features
β¦ let, const
β¦ Arrow functions
β¦ Template literals: Hello ${name}
β¦ Destructuring: const { name } = person;
β¦ Spread/rest operators: ...fruits
