On object looping:

    Object.keys(obj).forEach(function (key) {
        var value = obj[key];
        // ...
    });

Not the best thing, but it works in less lines than:

    var key;
    for (key in obj) {
        if (!Object.prototype.hasOwnProperty(obj, key) {
            continue;
        }

        var value = obj[key];
        // ...
    }

Plus, it avoids the async-function-in-a-loop problem (which is why I rarely use C-style `for` loops or `for-in` loops now).
