errbacker

Splits any function(error, result1, result2...) into two separate functions (errback and callback) via currying errback

Use like this:

var errbacker = require('errbacker')
var errback = console.error

var callback = console.log //your function where you want to push results

var withoutErrors = errbacker.curry(errback)
fs.stat('/tmp', withoutErrors(callback))
