Why the change to ChakraCore for Krom ?
I had to check JS engines for an unrelated project and ended up learning a lot about them. Primary reason is that Chakra is relatively small and I therefore get along with it much better. I managed to compile it directly via koremake, to port it to consoles and I got debugging support working. Speed is very similar (but overall V8 is faster), executable size is less than half (and it's a single exe without any libs).
