JavaScript Destructuring

Array Destructuring

Extract values from arrays easily.

```javascript const numbers = [1, 2, 3]; const [first, second, third] = numbers;

console.log(first); // 1 console.log(second); // 2 ```

Object Destructuring

Extract properties from objects.

```javascript const user = { name: 'John', age: 25, email: 'john@example.com' }; const { name, age } = user;

console.log(name); // "John" console.log(age); // 25 ```

Default Values

```javascript const { name, age = 18 } = user; ```

Key Takeaway

Destructuring extracts values easily. Use for arrays and objects. Saves code and makes it readable. Essential ES6 feature.
