🚀 JavaScript ES6+ Features

ES6 (and later versions) brought tons of cool, modern features to JavaScript that make your code cleaner, easier to read, and more powerful.

📚 Example: let, const & Arrow Functions

const greet = (name) => {
  let message = `Hello, ${name}!`;
  return message;
};
console.log(greet("Alex"));

🔄 Example: Template Literals & Default Parameters

function multiply(a, b = 2) {
  return `${a} x ${b} = ${a * b}`;
}
console.log(multiply(5));
console.log(multiply(5, 4));

📝 Example: Destructuring & Spread Operator

const person = { name: "Alex", age: 25 };
const { name, age } = person;
console.log(`Name: ${name}, Age: ${age}`);

const arr1 = [1, 2, 3];
const arr2 = [...arr1, 4, 5];
console.log(arr2);

Output will show here...

⚡ Quick Tips

let and const are block-scoped variables. Prefer const unless you need reassignment.
Arrow functions () => {} provide concise syntax and lexical this.
Template literals (`` `Hello ${name}` ``) make string interpolation easier.
Default parameters let you specify fallback values.
Destructuring extracts values from arrays or objects into variables.
The spread operator ... expands arrays or objects easily.
