Something I don't see on the front page, the first few screens of the Getting Started page, or the landing page of the API docs is the version of Lua being used. Edit: After binding a hotkey to hs.alert.show(_VERSION), it seems to be Lua 5.3. Edit 2: Oh Hammerspoon has an interactive console. Typing _VERSION in there would have been slightly simpler.
