 # Bob

 Bob is a lackadaisical teenager. In conversation, his responses are very limited.

 Bob answers 'Sure.' if you ask him a question.

 He answers 'Woah, chill out!' if you yell at him (ALL CAPS).

 He says 'Fine. Be that way!' if you address him without actually saying anything.

 He answers 'Whatever.' to anything else.


var Bob = function(input){.
  this.hey = function(input){
    if (input == input.toUpperCase() && input.match(/[a-zA-Z]/))
      return 'Woah, chill out!'
    else if (input.match(/\?$/g))
      return 'Sure.'
    else if (input.trim() == '')
      return 'Fine. Be that way!'
    else
      return 'Whatever.'
  };
};
