📘 Day 41: Modern JavaScript — ES6 Features

📘 Day 41: Modern JavaScript — ES6 Features

ES6 (ECMAScript 2015) introduced major improvements to JavaScript. Understanding these features is essential for writing clean and modern code.

🔹 let and const

Before ES6, we used var for declaring variables. Now, we use let and const for better scoping and reliability.

let name = "Rahul";
const age = 22;

name = "Rahul Naidu"; // ✅ Allowed
age = 23; // ❌ Error — const cannot be reassigned

🔹 Arrow Functions

Arrow functions provide a shorter syntax for writing functions.

// Regular function
function greet(name) {
  return "Hello " + name;
}

// Arrow function
const greetArrow = (name) => "Hello " + name;

console.log(greetArrow("Rahul"));

🔹 Template Literals

Template literals use backticks (`) and make string interpolation easy.

let course = "JavaScript";
let msg = `Welcome to the ${course} course!`;
console.log(msg);

🔹 Destructuring

const user = { name: "Rahul", age: 22 };
const { name, age } = user;
console.log(name, age);

🧠 Practice

Convert your regular functions into arrow functions and use template literals to build a greeting message dynamically.
