function forEachObject(object, callback, context) {
  for (var name in object) {
    if (hasOwnProperty.call(object, name)) {
      callback.call(context, object[name], name, object);
    }
  }
}
Executes the provided `callback` once for each enumerable own property in the
object. The `callback` is invoked with three arguments:

 - the property value
 - the property name
 - the object being traversed

Properties that are added after the call to `forEachObject` will not be
visited by `callback`. If the values of existing properties are changed, the
value passed to `callback` will be the value at the time `forEachObject`
visits them. Properties that are deleted before being visited are not
visited.
