JavaScript is the most misunderstood language out there. It looks and feels like it’s supposed to be slow as shit but it the very opposite: it’s actually one of the most throughly optimised languages out there, in face of the dynamism. I will forever be grateful for my line of work having had me study JS engines. It is really where the magic of computer science is in full display, and I have insane respect for the people who managed to pull this off. Here be dragons.
