iOS Facebook chat bot language

[patent10021]

Anyone know what language Facebook writes its chat bots in?

EDIT:

Seems it's just JS and JSON

Well JSON isn't a language, but if I were to put money on it, I would guess Hack? Its a Facebook created language which boils down to compiled PHP. They did this because at the scale FB is at standard PHP was to slow. Which is funny because they could have used other languages better suited for large scale, but stuck with PHP because it was easier for them to write a compiler for PHP than rewrite FB in something else.

So the API is in Hack but we write in JSON/JS?
