You need to do the following for this challenge:

  1. add the item to the end of the arr (push)
  2. remove the first item from the arr
  3. return the removed item

Hint: Steps 2 & 3 can be done in one line of code

Hi @dresc19 ,

The challenge is to remove the first element from the array.

  • Push item at the end of arr using push() method on arr.
  • Call the shift() method on arr to get the first item and store it in removed (create a new removed varaible)
  • Return removed .
