Browser global

Include the script in your html

<script src="MessageManager.js"></script>

And then use it anywhere in your javascript

//you can prefix with window
var mm1 = new window.MessageManager();
//or not prefix with window, because window is assumed in browser environments
var mm2 = new MessageManager();
