-Set a `hub` property using `Object.create(null)` to create a truly empty object that does not inherit properties from `Object.prototype` (which would be resolved if the event name matched one of the properties).

+Use `Object.create(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.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.push()` to add the handler
 to the array.
-
 For `off`, use `Array.findIndex()` to find the index of the handler in the event array and remove it using `Array.splice()`.
