56,414 PointsTo reference an item in an array we usually use the brackets after the array: array[position] We start counting the postition from zero, so the first item in the array is
grocery_list[0]
Ruby does have a .first methods for arrays and can be used like this:
grocery_list.first
But you don't use both together. Also the challenge says to put the item in a variable called first_item so don't forget to assign it.
first_item = grocery_list[0]

16,593 PointsThere are a few things here that are preventing you from reaching the correct answer:
- You need to create a variable called first_item.
- To access the first item in a standard array you use the arrays variable name followed by [0]. grocery_list[0] for example.
- Assign the first_item variable the first item in grocery_list like below.
first_item = grocery_list[0];
