Personally I like to use the same name for the object that I would typically
use in code that *uses* the object. For example I might use a variable
called 'dialog' for one of your Dialog objects, both in the constructor and
elsewhere.
The other rule I follow strictly is that if I create a variable for 'this',
then I do not use 'this' *at all* other than that one assignment. It's too
confusing to mix and match.
So, I'd write that code like so:
var Dialog = function() {
var dialog = this;
dialog.width = 400;
dialog.setWidth = function( width ) {
dialog.width = width;
}
}
