To OP - I think the resume is a clever format, and riding a language's popularity is a great way of putting yourself out there, especially as a junior.
To others, the "Traits" section -- how much impact does this really matter to the hiring managers? You're hired for what you know, but you're fired for who you are. Is it worth it to expand on these "traits", or is it a fluff area that can be replaced with something more meaningful?
I might use a different analogy -- it might be more like using a bike versus a motorcycle. You can run a delivery business on a bike, but you'd be able to do it with much less tinkering, if you were using a motorcycle.
