Built as an experiment inspired by some issues I ran into at work. Specifically, how to handle messaging between parts of a JavaScript application when we can’t know exactly when a component may load. I didn’t want to build an entire messaging system when we have a messging system at home (the browser’s event system). Instead, this focuses on providing a slim layer on top of events that lets you do some useful things like:

• Wait (for a set amount of time, or forever) for an event to fire.
• Listen for events from multiple sources.
• Run some logic when all handlers for a given message have fired (with access to whatever those handlers returned).
