You just print what you wrote and scribble on top of it. I suggest the first edit is on the computer though because there will be too much scratching. The concern here is that in addition to becoming hard to manage, other developers unfamiliar with the pattern may have a hard time grasping why it’s being used. Inside a constructor, the keyword this references the new object that’s being created. Within the Module pattern, variables or methods declared are only available inside the module itself thanks to closure.
