title: Passing an answer to choices in InquirerJS?
body: <p>How would I be able to get an answer from a previous question and pass on to the next question for choices for inquirerJS? I know the fact that it is asynchronous but i'm not sure how to create promises here. Any further insight and help would be great.</p>
  
  <p>Example:</p>
  
  <pre><code>var questions = [{
      name: 'menu',
      type: 'checkbox',
      message: 'Which food do you like eating?',
      choices: ['pizza', 'hotdog', 'hamburger', 'sandwiches'],
     }, {
      name: 'favorite',
      type: 'checkbox',
      message: 'Which one do you like most?',
      choices: answers.menu,   &lt;------- doesn't work because it is asynchronous
     };
  </code></pre>
