Another problem with not returning this arises, when you try to check whether your created object is an instance of NameMe or not.

var person = new NameMe('John', 'Doe');
person instanceof NameMe; // false, if you return a new object, which this solution does.

Since there are no prototype changes, it does not matter. Wouldn't best practice be to use "this" for any constructor function?

This is obviously an intro repo meant to teach about the constructor functions. A workaround that defeats the purpose of the constructor does not seem it should be a preferred solution.

Regex usually isn't the best for readability but it's a lot cleaner than how I removed the _ and =. I'm new to ruby so bare with me when I ask, are ternary operators prefered? I see them everywhere in the solutions but I've never liked the way read vs a regular if else.

Fixed it!

Thanks. What do you suggest in place of the switch? Using a Hash?

Thanks.

I have fixed the title. Could you point me other typos? Sorry but my native language is not English.

I've fixed description and added Ruby class definition. Haskell version author (@xcthulhu) really messed this up.

I think total is better, it stands for the sum of all previous results.
