📘 ES6 Introduction

ES6 (ECMAScript 2015) is a major update to JavaScript that introduced many new features and improvements. Here are some key highlights:

🚀 New Features in ES6

  • Arrow Functions → =>
    Simplify function syntax: 
    const add = (a, b) => a + b;
  • Template Strings 📜
    Use backticks (`) for multi-line strings and string interpolation: 
    const name = "Alice";
console.log(`Hello, ${name}!`);
  • Destructuring Assignment 🧸
    Extract values from arrays or objects: 
    const [x, y] = [1, 2];
const { a, b } = { a: 3, b: 4 };
  • Classes 🏛️
    Simplified syntax for object-oriented programming: 
    class Person {
  constructor(name) {
    this.name = name;
  }
}
  • Modules 📦
    Use import and export for modular code: 
    // math.js
export function square(x) {
  return x * x;
}

// app.js
import { square } from './math.js';
