Maybe it would be more semantic to just have the function return null or undefined if the string is null or undefined?

In my opinion, null and undefined should be considered a developer mistake and throw.
if (string === null || string === undefined)

Good point. Should it throw for anything other than a string?

I'd argue null or undefined as slugified should exactly an empty string. I think throwing on this would generally cause more issues than help. |

If undefined is passed in, this will return an empty string instead of an error. Not sure if this error is preferred to just returning an empty string though.
