function settingsProvider is global

[Molesmalo]

Hi D.

Requesting a small change on line 17:

	settingsProvider = () => {

should be

	let settingsProvider = () => {

As there's no var, let, const keywords, it's declared as global, thus leaking from the module.
I would also recommend adding (I forgot to add it on the examples!)

"use strict";

Thanks!
