Ruby Ruby Collections Ruby Arrays Removing Items From Arrays

Nots sure with this one

grocery_list = ["milk", "eggs", "bread", "ice cream", "carrots", "potatoes"] last_item = grocery_list.pop first_item = last_item.shift[0]

grocery_list = ["milk", "eggs", "bread", "ice cream", "carrots", "potatoes"]
last_item = grocery_list.pop
first_item = last_item.shift[0]

You are close! Just keep in min that shift is very similar to pop. The only thing shift does differently is that it removes the first item instead of the last item. It returns the first item as well, like the pop method does.

So this means you should call the method on the grocery_list array, not the first_item string. Also, you shouldn't pass in an argument to the shift method; remember shift already knows by default to remove the first element and isn't expecting an index.

I hope this helps :grin:
