Event

The Event class allows you to fire (broadcast) global events and subscribe to them. Here’s an example:

//// SENDER
let data = true; // this could be any value
eventName = "Some Name";
Event.fire(eventName, data);

//// RECEIVER
let SNCallback = function(data){
  log("callback: " + data);
};

function start(){
  Event.addListener("Some Name", SNCallback);
}
function onRemove(){
  Event.removeListener("Some Name", SNCallback);
}
