I can confirm, from looking at the code.
It uses CSS / LESS for highlighting, and CoffeeScript for client-side programming (eg, the fuzzy completion[0], or the autocompletion).
The surprising part is that the editor doesn't seem to be a fork of either Ace or CodeMirror, the two big guys in the field. The highlighters (ie, syntax files) are in CSON. Ace is probably the closest, but it uses a completely different structure[2].
A negative impact of that is the low number of syntax files. However, there seems to be a 1-to-1 equivalence to tmLanguage (TextMate) syntax files[3].
