Their code pretty much reflects this philosophy: Plain, boring and concise with no fluff. You can easily read it top to bottom without needing to jump around to get the bigger picture. There is very little noise there. There is this pragmatic minimalism to it. You won’t find layers of abstractions for abstraction’s sake. The biggest “debate” - if you could even call it that - usually revolves around how to structure data or where to put side effects.
Clarity is key indeed.
