title: How to do a recursive prompt in Yeoman with promises?
body: <p>I'm trying to figure out how to do a recursive prompt with a yeoman generator using promises. I am trying to produce a form generator that will first ask for a name for the form component and then ask for a name (that will be used as an id) for each input (ie: firstName, lastName, username, etc.). I've found answers for this question using callbacks but I would like to stick with promises. Below is the code I have so far and what I am attempting to do for the recursion but is not working. Any help and advice is appreciated thank you in advance!</p>
  
  <pre><code>const Generator = require('yeoman-generator')
  
  const questions = [
    { type: 'input',
      name: 'name',
      message: 'What is the name of this form?',
      default: 'someForm'
    },
    {
      type: 'input',
      name: 'input',
      message: 'What is the name of the input?'
    },
    {
      type: 'confirm',
      name: 'askAgain',
      message: 'Is there another input to add?'
    }
  
  ]
  
  module.exports = class extends Generator {
  
  
    prompting() {
      return this.prompt(questions).then((answers) =&gt; {
        if (answers.askAgain) {
          this.prompting()
        }
         this.userOptions = answers
         this.log(this.userOptions)
      })
    }
  
  }
  </code></pre>
