With regards to JavaScript Objectorientated Challange - How will js objects interact with each other, if they are stored in multiple js files? Is there a special way to link link them together? For example - In Game js I create a method that receives event as an argument, and this argument is passed somehow to app.js file event listener callback method. I don't understand how is this possible?

So functions in one file can be called from code loaded from another file.
