ArrayArray.prototype.popintermediate

Array.prototype.pop() — remove the last word

📖 Usage Example
const words = ['foo', 'bar', 'baz']
const last = words.pop()  // → 'baz'
words  // → ['foo', 'bar']

Use pop() to consume the last string element from a queue or word list.

Array.prototype.pop() — string arrays

pop() works on any typed array, not just numbers. This exercise applies it to a string array to remove and return the last word in a list.

Challenge: Implement removeLastWord(words) that pops and returns the last string from the array.

removeLastWord(['hello', 'world']) // → 'world'
removeLastWord(['only'])           // → 'only'
💡 Hints (2)
  • • `pop()` works identically for string arrays — it removes and returns the last element.
  • • The return type is `string | undefined` because `pop()` on an empty array returns `undefined`.
