async.forEach({1: 'hello', 2: 'world'},
  function(key, value, done) {
    console.log(key, value);
    done();
  },
  function fin(err) {
    if (err) { console.log(err); }
  });

This may be useful but the same can be achieved with:

var obj = {1: 'hello', 2: 'world'};
async.forEach(Object.keys(obj),
  function(key, done) {
    console.log(key, obj[key]);
    done();
  },
  function fin(err) {
    if (err) { console.log(err); }
  });
