Different way less code

As I am working on my JavaScript and trying different things, can anyone see a reason why this can not be written like I have it? Much less code, works the same!

var questions = 3;

var adjective = prompt('Please type an adjective, there are ' + questions + ' questions left');
questions -= 1
var verb = prompt('Please type a verb there are ' + questions + ' questions left');
questions -= 1
var noun = prompt('Please type a noun there are ' + questions + ' questions left');

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

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

You can totally write code like that but I don't think 3 lines of saving means much especially where underlying logic is same which is why it works same. However, I do think use of questionLeft in the video is tedious so I'll say yours is better although It seems like the code from video is just used as stepping stone for improvement on future video.

This exercise was more about trying to do this in a different way and really get a much stronger grasp. I am not trying to out-do the Dave here as I know better :) , instead I am just trying to learn.
