+- Use `Object.create()` with an argument of `null` to create an empty `hub` object that does not inherit properties from `Object.prototype`.
 - For `emit`, resolve the array of handlers based on the `event` argument and then run each one with `Array.prototype.forEach()` by passing in the data as an argument.
 - For `on`, create an array for the event if it does not yet exist, then use `Array.prototype.push()` to add the handler
 - to the array.
