Eris is a class, so should be called with newas with the original examples

https://github.com/abalabahaha/eris/blob/dev/index.js#L5 Here you can Eris is a function that returns new Client class.

According to MDN:

4. If the constructor function returns a non-primitive, this return value becomes the result of the whole new expression.

So if I understand correctly, the Eris() function returns a class which is a non-primitive. It means that both Eris() and new Eris() return the same result.

Yes you are right. Actually when I was using typescript I got a type error so I replaced new Eris with Eris.

I'd argue that if you're using typescript, you're already familiar with what to do and not to do. That being said this technically is a minor bug, but I have my reservations (aside from the point I just made) with this being the solution. I'll loop back to it once the API facing features are sorted out
