Just curious as to the reason why stateBefore needs to be a function rather than a const. Is that intentional?

No reason, a variable would work great :)

@Trevor good course! and a much needed one, thanks.
Think needs to be updated for Enzyme. Also reducers should not mutate the state. The current tests are not checking and enforcing the no mutation of state. You need to perhaps assign the results of the function call to a const and then deep freeze the const.
