One thing to note about self specifically; by default, self as an alias for window. If you override that with a var self, you're fine, but if you forget to add that line and you use self in an inner scope assuming it's referring to your outer scope, there's a potential for some nasty bugs that can be hard to track down.

For that reason, I tend to use some other identifier: that, _this, some variable denoting what type it is, such as app if it's referring to something I'm calling an "application", view if it's a view, etc. In this case, as long as you're in strict mode or properly linting your code to object to using undefined variables, you'll get notified if you forget to add that alias.
