At some point in Martins book, he mentioned a forgotten codebase from one of his friend that was solely composed of tiny functions but yet achieve a fairly complex effect. That's the kind of feeling I had working at Laravel (admittedly it's been a few years). React codebase, on the other hand, seem less human-friendly, it seems to require some prior knowledge of the code to be able to dive into.

Same here, I was looking at linux kernel network code lately and I was surprised by how clean and easy to follow it was.
