Composition So how does composition work? Just wrap an object in a function, and make the function return that object. Easy! Here’s a simple example. Imagine that you want to create different animals, like cats, birds, and mice. These animals all share similar properties: legs, eyes, and an ability to make sounds. So it makes sense to start with a general animal object as a template, and then use that template as a base to create specific animals. Here’s how you can do that using composition. Create a function called animal.
