    Hi all!

    Originally the script engine being used was "V8", the same as being used by WebKit/Blink.

    However, it got replaced by a newly written engine called "V4", as a pun on the old one.

    The main reason was that V8 is built around just-in-time compiling, which is not allowed on restrictive platforms such as iOS.

    So V4 can run in interpretive mode on those platforms and use JIT on platforms where that is possible.

    Cheers,
