Generators are functions you call to produce an iterable object. We don't need to implement iteration for the Load class. Given that JavaScript does not have interfaces, Iterable is more of a convention: Source: A value is considered iterable if it has a method whose key is the symbol Symbol.iterator that returns a so-called iterator.
