> This is one of those things that is completely lost on someone who has never written in a low level language. I automatically assume JavaScript developers to be completely oblivious to this entire class of software development knowledge. This is a shame because not only are there lots of developers who write JS that have low-level backgrounds there are also a lot who haven't and are still interested. It seems rather snobby to jump in and write off a bunch of people because of the language they use on the assumption that they use the language without being aware of the implications. On OOP versus more cache friendly approaches and branch prediction this talk from CPPCon 2019 is great: this video The interesting result is that although the DoD approach is eventually faster a branch misprediction causes havoc until uncovered.
