Javascript Async style memory usage

gistfile1.md

Async/await style (i.e. how most of this package's code is written)

module.exports = async function() {
  await delay(1)
}

function delay(duration) {
  return new Promise(resolve => setTimeout(resolve, duration))
}

Promise without async/await

module.exports = function() {
  return new Promise((resolve, reject) => {
    setTimeout(resolve, 1)
  })
}

Simple callback

exports.runner = function(cb) {
  setTimeout(cb, 1)
}

Fibers/futures

var Future = require('fibers/future')

exports.fiberRunner = function() {
  var fut = new Future

  setTimeout(function() {
    fut['return']()
  }, 1)

  return fut.wait()
}
