Signal Emitter
When I released JS-Signals I decided to create a document explaining the difference between different kinds of Observers and the possible pros and cons of each pattern, and as you can see on the document every approach has its pros/cons and depending on the scenario the recommended approach might change.
Before coding JS-Signals I was using a very basic EventEmitter “class” that could be used to listen/dispatch arbitrary events but ever since I released JS-Signals I almost didn’t used arbitrary events anymore (because of the benefits of using a Signal), but a couple weeks ago I had to propagate changes on my model classes to the UI and the changes are coming from many different inputs, so the easiest way to keep everything in sync was to dispatch events every time my model objects updated with a new value. In that case it is way easier to use a string ID for the event type than to create a new Signal object manually for each value, since the project was already using Signals everywhere I decided to code a simple EventEmitter that would use JS-Signals internal mechanism (so I could use the advanced features if needed) but still allow arbitrary event types.
