component-emitter

Hello I have an error during installation normally the same version has the same checksome no?

The Emitter Component is Failing License Check. Please refer to the Issue-1 created within the emitter-component-test GitHub Repository.

I am trying to learn more about this library but i had some questions. well in all honesty, i am a little lost on how this works. 1) If i take this example in the Readme If i understand correctly, you can create a new Emitter and register listeners to it. When you do, you create it with an event type. then using emit, you pass in that event type. then some listners like will run what ever you pass in is that correct so far? 2) To follow up, may i ask for an explanation on this example what does this do ? does it mean it uses the passed in object as a way to detect for events? I found another library that used the prototype of an advance nodejs class into the constructor, but i am not sure what changes that vs an empty create of a instance. thanks in advance!
