Is there a more concise method of doing this?

Do we really need to type a bunch of code for this? What if we have 100 questions to ask?

You could use an array to store the questions, then loop through all of them and store the answers to these questions in another array.

var questions = ['Please type an adjective', 'Please type a verb', 'Please type a noun'];
var questionsLeft;
var answers = [];
while(questions.length > 0) {
  questionsLeft = ' [' + questions.length + ' questions left]';
  answers.push(prompt(questions.shift() + questionsLeft));
}

alert('All done. Ready for the message?');

var sentence = "<h2>There once was a " + answers.shift();
sentence += ' programmer who wanted to use JavaScript to ' + answers.shift();
sentence += ' the ' + answers.shift() + '.</h2>';
document.write(sentence);

The array methods used here are shift() and push(). The shift() method removes the first element from an array and returns that element. The push() method adds one or more elements to the end of an array.

Beautifully implemented solution! There's a lot to learn from your approach to this challenge. Thanks for sharing! Turned into a note for future reference. :)

Haven't got to arrays and loops but I'll look into it once I reach the lessons. Thanks a bunch!
