It's not unique to javascript. The equivalent in ruby would be `state = behavior.init.class = Method ? behavior.init : {}` After looking it up, I don't disagree that Python looks a lot prettier, though: `state = behavior.init() if callable(behavior.init) else {}` That made me curious if Ruby had anything like Python's `callable`, but I couldn't find anything. This is my best effort in Ruby for aesthetics: `state = if behavior.init.respond_to? :call then behavior.init() else {} end` In the end, I agree, Javascript looks much worse than the equivalent Python in this case. Unfortunately I don't get a choice of python on the frontend :p
