> Interestingly, JavaScript also has `Array.prototype.reduceRight`, but it's not equivalent to a `foldr`. It processes the list from right-to-left, so is approximately equivalent to `reverse` followed by `foldl'`. I don't understand how that's different in practice. Can you elaborate?

Although `foldr` accumulates the result right-to-left, it processes the list left-to-right, which allows it to short-circuit. `reduceRight` processes and accumulates right-to-left, so it doesn’t have the short-circuiting ability of `foldr`.
