September 18, 2020 - If both of these conditions evaluate true the count variable is incremented by one. One question that I had while solving this problem is what happens if there isn't an even number of sub-arrays that satisfy the conditions. After some research I discovered that JavaScript evaluates the indexes that don't satisfy the conditions as undefined.
