After [![Build Status][1]][2]

Invoke callback after n calls

Status: production ready

Example

var after = require("after")
    , next = after(3, logItWorks)

next()
next()
next() // it works

function logItWorks() {
    console.log("it works!")
}

Example with error handling

var after = require("after")
    , next = after(3, logError)

next()
next(new Error("oops")) // logs oops
