Fixes my own issue #60; Read that for more info

1. a lot of your committed code is unrelated to your changes
2. you also don't have any tests.
3. I don't really have a preference, but is pwn the best stylistic option here?
4. Is it wise to mix in modern es6 stuff like you did with const?

1. That's just my IDE. I'll fix that when I have time
2. I have. Didn't it get commited? I'll check later
3. Just an idea
4. I'm just used to es6.

I'll fix them when I can. A bit busy now
