They didn’t call .pop on the array

  • In the example above, calling .pop() on the newItemTracker array removed item 2 from the end.

well, they didn’t call .pop( on the array, I almost got lost it trying to follow the example to the T.

const newItemTracker = ['item 0', 'item 1', 'item 2'];
const removed = newItemTracker.pop();

newItemTracker is most certainly an array, and pop is most certainly called on the array
