Showing Rex how I'd do it

gistfile1.coffee

getUserObjectSomehow = () ->
    id: 5
    logged_in:true

do_something = (user) -> "> Logged in user #{user.id}:  #{JSON.stringify(user, null, 4)}" unless !user.logged_in
  
# Admittedly this is mildly dependent on underscore or lodash. 

log = console.log.bind(window) 

printSomething = _.compose console.log, do_something
 
user = do getUserObjectSomehow
 
printSomething user
