💡 Quick Tip
Here are 5 JavaScript array methods every developer should know:
1. map() - Transform Array
const numbers = [1, 2, 3, 4, 5];
const doubled = numbers.map(n => n * 2);
// [2, 4, 6, 8, 10]
2. filter() - Filter Array
const numbers = [1, 2, 3, 4, 5];
const evens = numbers.filter(n => n % 2 === 0);
// [2, 4]
3. reduce() - Aggregate Array
const numbers = [1, 2, 3, 4, 5];
const sum = numbers.reduce((acc, n) => acc + n, 0);
// 15
4. find() - Find Element
const users = [{id: 1, name: 'Alice'}, {id: 2, name: 'Bob'}];
const user = users.find(u => u.id === 2);
// {id: 2, name: 'Bob'}
5. some() - Check Condition
const numbers = [1, 2, 3, 4, 5];
const hasEven = numbers.some(n => n % 2 === 0);
// true
