Tell us what’s happening:
I think the last task of the page might confuse people where it says:

removedFromMyArray should only contain ["cat", 2] .

But that array is what we’re supposed to remove and this array should stay:
[“John”, 23]

Please correct me if I am wrong.

Your code so far

// Setup
var myArray = [["John", 23], ["cat", 2]];

// Only change code below this line
var removedFromMyArray = myArray.pop();

Challenge: Manipulate Arrays With pop()

pop() removes the last item from an array and stores it in a variable. So the initial array, if called after the pop() action will exclude the removed item.

You are not wrong :slight_smile:

.pop() removes the last element from an array and returns that element.

Look at the name of the variables:

myArray should only contain [["John", 23]] .

removedFromMyArray should only contain ["cat", 2] .

they are correct. myArray starts as [["John", 23], ["cat", 2]], you remove the last element with pop, and then it remains as [["John", 23]]
meanwhile the removed element is stored in removedFromMyArray
