ES6 Overview
ES6 introduced major improvements to JavaScript, including modern syntax.
Learning Goals
The Core Concept
ES6 (also known as ECMAScript 2015) was a massive update to JavaScript. It introduced many new features that made writing JavaScript easier, faster, and more robust.
Key features include 'let' and 'const' for variables, arrow functions, template literals (using backticks), destructuring, and the spread operator.

Code & Implementation
// 1. Template Literals (Backticks)
const name = "John";
console.log(`Welcome to the team, ${name}!`);
// 2. Object Destructuring
const user = { id: 1, role: "admin" };
const { role } = user;
console.log(role); // "admin"
// 3. Spread Operator (Copying arrays)
const oldCart = ["Apples", "Milk"];
const newCart = [...oldCart, "Bread"];
console.log(newCart); // ["Apples", "Milk", "Bread"]Expected Output
Welcome to the team, John! admin [ 'Apples', 'Milk', 'Bread' ]
