# 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
    next() // does nothing

    function logError(err) {
        console.log(err)
    }
