Best Practice but adding a comment would have sent the solution to Mars!
This case should be added
What a wonderful solution!

I'll fix it
That's exactly your problem, you should be using them.
Not a kata issue, check what the delimiters value is.
['some', 'strange', 'string'] should equal ['some strange string']
['1', '2', '3'] should equal ['1+2', '-', '3']
I think there is something wrong with those tests
needs random tests
No random tests.
Yes, I just wanted to make it obvious :)
Maybe you did it this way for illustrative purposes but you may as well simplify, no? (65 + 1 === 64)
