This is good, but some of the advice isn't quite right. For instance "self" is a reserved keyword in JavaScript, so often people use "_self" instead. And camel casing variable names is right, unless they're constants, in which case "THIS_IS_A_CONSTANT" is more appropriate. Too nit picky?
I find that much more readable, especially when looking at code completion in the IDE, I can always tell whether a property is a method or not.
For example, you might have an object foo that has a property called isBar. I like being able to tell that that is a function that returns a true or false value, as opposed to is_bar which just holds the boolean value.
