  ;

lateral = Lateral.create(function (complete, item, i) {
  setTimeout(function () {
    console.log(item);
    complete();
  }, 500);
}, maxCallsAtOnce);

lateral.add(['a', 'b', 'c', 'd']).when(function () {
  console.log('did all the things');
});

lateral.add(['d', 'e', 'f', 'g']).when(function () {
  console.log('did all the things');
});

API

Creates a Sequence-ish object for the purpose of synchronizing other Futures.

Core

• lateral = Lateral.create(handler, n)

  • create a Lateral that will execute fn on each item to do at most n things at once

• lateral.add(arr) - adds arr to be handled by fn

• lateral.add(arr).when(callback)

  • Fires callback when all items in the arr batch have been handled
