A bus is just like an EventStream, but it lets us push values into the stream manually instead of attaching it to a source, and it also allows plugging other EventStreams and properties into the bus on the fly.
Here is an example that demonstrates how to create a bus and various methods provided by a Bacon.Bus instance. Place this code in the index.js file:
var bus1 = new Bacon.Bus();
bus1.onValue(function(event){
console.log(event);
})
bus1.push(1);
bus1.push(2);
var bus2 = new Bacon.Bus();
bus1.plug(bus2);
bus2.push(3);
bus1.error("Unknown Error"); //pushed an Bacon.Error
bus1.end();
bus2.push(4); //this will not be pushed as bus has endedThe code is self explanatory. The output of the above code is as follows:
1 2 3
