Asynchronously iterate an array as a series. Similar to async.eachSeries, but as a small module.

Install through npm

npm install each-series

var each = require('each-series');

each([1,2,3,4,5,6,7], function(el, i, done) {
	setTimeout(function() {
		console.log(el);
		done();
	}, 100 - (el * 10));
}, function(err) {
	console.log('Done!');
});

The module is only one function

each(array, iterator, [callback])

The callback is optional.

If an error is passed to the done function passed to the iterator, iteration will be stopped and the callback will be invoked with the error.
