Why do you have to add questionsLeft again after every prompt?

Why do you have to add questionsLeft again after every prompt? Why can't i just add questions -= 1 after every prompt like the example below? If I do not add: questions -= 1; questionsLeft = " (" + questions + " questions left)"

then the questions variable does not decrease by 1.

Example: var questions = 3; var questionsLeft = " (" + questions + " questions left)" var adjective = prompt('Please type an adjective' + questionsLeft); questions -= 1; var verb = prompt('Please type a verb' + questionsLeft); questions -= 1; var noun = prompt('Please type a noun' + questionsLeft); 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);

The "questionsLeft" string tells the user how many questions are left to answer, and to be accurate it must be re-created for each question. Simply reducing "questions" doesn't change the message that will be shown.
