We write a revealing module pattern by starting with a self-executing anonymous function also known as an IIFE (immediately invoked function expression).

This runs a function and sets it's return value as our module's value. If we return an object of methods, then those methods are what other modules have "public" access to. What's nice about this, is we can create any variables within the function and no other modules have access to them unless we expose them via our return object.
