Array.prototype.push() — collect evens with forEach

📖 Usage Example

const evens = []
[1,2,3,4,5].forEach(n => { if (n%2===0) evens.push(n) })
evens  // → [2, 4]

Use push() to collect matching elements into a result array during iteration.

Collecting values with push

A common pattern: use forEach to iterate and push to collect matching elements into a new array.

const evens: number[] = []
[1, 2, 3, 4].forEach(n => { if (n % 2 === 0) evens.push(n) })
// evens === [2, 4]
