Double check this one, I'm surprised it is passing. Notice the latter half of the string: and return a new array
Check out the differences between each and a method like map
- What do they take?
- What do they return?
Otherwise, nice work!

Good call! Looks like the each method lets us do something with each element of an array without actually changing it, like a for each, while returning the original array. Wheras map returns a new mutated array! And the test wasn't passing, but now it is 😃
