V8 and the Julia compiler work in quite different ways - because they solve quite different problems. In particular, Julia’s compiler only works well on code that is "type-stable", whereas V8 has no such limitation.
- kuter 6y agoI know that V8 does some interesting stuff with it's types. Julia's creators considered supporting optimization while designing the language. Whereas the first javascript engine that even generated machine code came much later it's creation. Js has weird features like being able to set a getter function to a array index. There was a memory corruption bug in V8 that the implementation of `Array.sort` would call a getter function in the array that would change the size of the array causing a memory corruption. This was used in a exploit. Creators of V8 created a domain specific language called Torque to implement the language lol.
