Array.prototype.push() — build an array with a loop

📖 Usage Example

const result = []
for (let i = 1; i <= 3; i++) result.push(i)
result  // → [1, 2, 3]

Use push() inside a loop to progressively build an array one element at a time.

Building arrays with push

A classic pattern: start with an empty array and push values in a loop.

const result: number[] = []
for (let i = 1; i <= 3; i++) result.push(i)
// result === [1, 2, 3]
