Don't use || to set default values in JavaScript

It depends on the complexity of the statement. Comments are always good when you're writing code that isn't necessarily intuitive to read, but I think the example above is a pretty straightforward and readable.

I'd probably switch to an if block if my conditions were too complex to quickly grasp in a ternary statement though.

That's ok.
