Quick Tip: JavaScript Array Methods You Should Know

💡 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
