, ee1 = new EE

es.listen(ee1, 'thing', ['one', 'two'])
.listen(ee2, 'data', ['two', 'three', 'four'])
ee1.emit('thing', 1, 2)
es.once('data', function(state) {
// state will be === {
// one: 1
// two: 10
// three: 20
// four: 30
// }
})
ee2.emit('data', 10, 20, 30)
es.once('data', function(state) {
// one and two will be cleared!
})
ee1.emit('thing') // since "one" and "two" are undefined, it'll clear those states
API
es.listen(emitter, eventName, 'list', 'of', 'bindings') -> es
listen to an emitter
on eventName
. when that emitter emits that event name,
it will update the state object. the state object will then emit a 'data'
event
containing the current state.
