Didn't Facebook also develop is JIT for their PHP? Or have they moved on frmo PHP?

Hack/HHVM no longer has a goal to be PHP compatible, but it looks pretty much the same. It does have a JIT: https://hhvm.com/blog/2027/faster-and-cheaper-the-evolution-...

Do we know anyone outside of Facebook uses Hack/HHVM in production?

Slack is the only other company you might have heard of (but still, Slack).
