function getObjectValues(obj) {
  var values = [];
  for (var key in obj) {
    values.push(obj[key]);
  }
  return values;
}
Retrieve an object's values as an array.

If you are looking for a function that creates an Array instance based
on an "Array-like" object, use createArrayFrom instead.

@param {object} obj An object.
@return {array}     The object's values.
