The solution code is very refactored and should include some comments in order to understand how it returns an array.

You need to have an understanding of 'self', or at least that it can be implicitly called, before you can complete this lab! There is no explanation of this concept in this lab or before it in any lab on the Web Development Fundamentals track. I struggled with this for a long time before asking for help from a teacher. Please add an explanation of 'self' to this lesson or to a lesson that comes before it in the Web Development Fundamentals track!!

This lab nonchalantly using classes as if everyone should have a full understanding of what they are by now even though there has been no mention of them anywhere in the pre-work leading up to this.

This lab didn't give much background into splats, beforehand, even after looking at the extra resource I was still confused on what to do. I wish there was a full lesson on splats and pulling a 'key' from a given 'value' beforehand.

I'm having an issues getting started on this lab. The first part of spec is passing just an array with the word Panama. When I binding.pry right here I am just getting an array with 1 element of "Panama"

class Hash
def keys_of(*arguments)
binding.pry

Hi,
I had to use the 'self' keyword here to refer to the instance of the class that my class instance method was operating on. I don't believe this had been introduced before this lab.

Thanks

This lesson strikes me as "figure out how to use the splat operator on your own". Could be a bit more instructional in my opinion.
