Processing js: .pde or .pjs?

While looking at examples of processing.js on the web, I have noticed that both .pde and .pjs file formats have been used for processing sketches. Could someone please explain the difference to me between using these two formats? Are there pros and cons to each? I have been developing in the javascript mode of the processing IDE, which defaults to .pde. If I were to change to .pjs, would I no longer be able to run from the processing IDE? Is it possible to call straight javascript functions when using .pjs? I have seen people call functions like window.innerWidth in pjs files, but am not sure how much javascript can be used.

Any insight would be greatly appreciated! :)

I might hazard a guess that .pde is pure Processing while .pjs could contain javascript inside as well, in which case it will only be run in the context of http://processingjs.org/. The IDE will fail at trying to run code with javascript inside it, regardless of if the code's extension is pde or pjs. The processingjs way of running code will be able to run code with javascript, again regardless of the code's extension. In processingjs, you can mix the two very well.

Thanks for your input! From what I've experimented with so far, that makes a lot of sense.

I forgot to mention that I actually got javascript working in my pde file using the method explained in promax's guide to processing.js. However, this requires interfacing javascript inside processing and calling javascript functions via the javascript object in processing. I am not sure if this is a wise alternative to just using a .pjs file and calling straight javascript.
