In this video, we're going look at how JIT folds constants and optimizes functions buy inlining and then folding them. We shall also see a couple of examples where the compiler will refuse to fold code that would seem to be easy to fold. Note: At (8:30) I've made an editing error and the music gets very loud for ~10s and then it goes back down to normal volume, sorry about that. ♦ link to shift trick video: https://youtu.be/VxiZ7tV-XkM
