Question re Battleship game in Ch. 8: why functions are not part of our objects?

[mashablair]

I have a question about this Battleship code in Chapter 8. We have the model, view, controller objects; however, some functions, like helper function parseGuess() and handler functions, like handleKeyPress are not a part of the objects.

For example, why couldn't we make the parseGuess() function a method of controller object? And is init function always a stand-alone function because it needs to start everything?

Thank you so much!

Possibly because those functions could be used at a later time by another js-program. However you can move the functions into the models object. Those methods will yield the same result; however you'll need to make sure you use "this." when calling them from within the object.

Hope this helps
