Question

I was reading this smooth CoffeeScript book and it had a code

confirm 'Shall we, then?', (answer) -> show answer

This is supposed to get the answer from the confirm and show it / I changed the ‘show’ to console.log and it doesn’t seem to execute it. what am I missing.

thanks

Answer 1

confirm() doesn’t take a callback. Unless this guy made his own confirm function, that won’t work. The cs for that compiles to

confirm("Shall we, then?", function(answer) {
  return console.log(answer);
});

confirm() returns true or false, so you can just use it as a conditional.

console.log "They answered yes" if confirm "Shall we, then?"
