Lesson 5: reduceRight

After the length of the reduce() lesson this is going to seem comically short.

reduceRight() does the same thing as reduce() but it starts at the end of the array and works backwards.

It's the same as calling reverse() on an array first (which, you guessed it, reverses an array) and then .reduce().

Most JavaScript developers don't know this exists, I'm only including it for completeness and so you have another tidbit of knowledge to make you look good!
