co-async

DEPRECATED. please use bluebird.map, it can control concurrency limit now. http://bluebirdjs.com/docs/api/promise.map.html

quick start

var coAsync = require('co-async')
var initValues = {a: 1, b: 2, c: 3, d: 4}

var start = new Date
var values = yield coAsync.map(initValues, 1, function * (v, k) {
  yield sleep(10)
  return v * 2
});
(new Date - start).should.aboveOrEqual(40)
values.should.eql({a: 2, b: 4, c: 6, d: 8})
