Ruby Ruby Collections Ruby Arrays Removing Items From Arrays

Posted by Ron L

Using .drop(2) in Ruby version 2.2.1 drops the first two items (not the last two)

x = ["eggs", "bread", "butter", "water", "milk"] y = x.drop(2) => ["butter", "water", "milk"] y => ["butter", "water", "milk"]

using .drop(2) returns the array with the first two elements removed. It does not create the new variable out of the last two elements of the array as the video states.

To clearly explain the drop method, I finally made it like this: array.drop(n) is the same array but without the first n items

You are right. I think Jason's example array in the video just isn't very clear, since there were 4 items inside and he drops 2 from it. He says "you'll see our variable contains the last two items in the array" but he doesn't explain that it's because the first two were dropped, not because drop returns the last two.
