Elyses Enchantments - Task 3

Hi!

I have an issue with “Task 3”; it says to insert a card at the top of the stack for which I used “unshift” method, but I didn’t pass the test. Then I noticed in “Hints and Tips” the following: " There is a [built-in] method to add a new value to the end of the array."

So is it my mistake, is it top or end of the array? Thank you!

Typically when an array is used to represent a stack, the top of the stack is the end of the array.

The example clears up the ambiguity:

const newCard = 8;
insertItemAtTop([5, 9, 7, 1], newCard);
// => [5, 9, 7, 1, 8]

The tests expect the new value at the end of the array. unshift adds a new value to the start of the array.
