flow-stoplight

$3

A simple flow control mechanism.

Has two modes: "go" and "stop".

Starts stopped.

``js
var stoplight = new Stoplight()

stoplight.await(function(){
// this will called when the stoplight is set to "go"
// if its already "go", it will be called on the next frame
})

// starts stopped
stoplight.go()
`

$3

Here is a class that has some async intialization process,
but can have its asynchronous method called immediately w/o breaking.

`js

function MyClass() {
var self = this
self._stoplight = new Stoplight()
asyncInitialization(function(){
self._stoplight.go()
})
}

MyClass.prototype.asyncMethod = function(cb){
var self = this
self._stoplight.await(function(){
// handle the method here and you can be sure that
// the async initialization has finished
})
}
