Array.prototype.pop() — returns undefined for empty array

📖 Usage Example

const arr = []
arr.pop()  // → undefined  (empty array)

pop() returns undefined when called on an empty array — guard against this if needed.

Array.prototype.pop() — empty array

Calling pop() on an empty array does nothing and returns undefined. The array remains empty and no error is thrown.

Challenge: Implement popEmpty() that calls pop() on an empty array and returns the result.

popEmpty() // → undefined
