Array Mutation Methods

Mutation methods change the original array. This lesson focuses only on push() and pop() so learners can see how an array grows and shrinks at the end.

Example

javascript
const queue = ['first', 'second'];
queue.push('third');
const removed = queue.pop();

Your Task

  1. Create queue with first and second, then use push() to add third and pop() to store the removed item in removedItem.
  2. Display first,second | third in #output.
Hint 1
1 / 2
HINT 1
