1. Destructuring Objects and Arrays
Destructuring makes it easy to extract data from objects and arrays.
// Destructuring objects
const person = { name: 'Alice', age: 25, city: 'New York' };
const { name, age } = person; // Extract 'name' and 'age'
console.log(name, age); // Output: Alice 25
// Destructuring arrays
const colors = ['red', 'green', 'blue'];
const [first, second] = colors; // Extract first and second elements
console.log(first, second); // Output: red green
