Other modules can then import those properties and methods if they want to use them. Anything in the module that isn’t exported can’t be seen or used by any other module, making it essentially private to that module. Let’s look at some simple examples that illustrate how modules work. 36 Chapter 1 ■ Level Up! js extension. It’s no more complex than that. ■■Note If you’ve used earlier versions of JavaScript, this might come as surprise to you. You no longer need to wrap your module code in an immediate function to isolate it from the global scope, and you don’t need any special syntax to define the file as a module.

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.
