Story

One day, a dot instance was born:

dot = require("dot-event")()

Each time dot went into a composer, the composer added some functionality to it:

module.exports = function(dot) {
  dot.any("sayHi", function() {
    console.log("hi!")
  })
}

The user had an easy time composing their dot:

require("./hi")(dot)
require("./whatsUp")(dot)
require("./yo")(dot)

dot.sayHi()

Far away, a library author noticed the first argument behaves as expected...

dot.any("say", function(arg) {
  console.log("arg:", arg)
})

dot.say("yo") // arg: yo

But the second argument does not!

dot.any("say", function(arg, opts) {
  console.log("arg:", arg)
  console.log("opts:", opts)
})

dot.say("yo", "hello")
// arg: hello
// opts: { dot: <DotEvent>, ns: "say", prop: "yo", propArr: ["yo"] }

And adding even more arguments only added more props!

dot.say("sup", "yo", "hello")
// arg: hello
// opts: { dot: <DotEvent>, ns: "say", prop: "sup.yo", propArr: ["sup", "yo"] }

And thus their journey began...
