A better way of doing this? See my code below, it works, does not need an if statement and is more straight forward.

var randomNumber = getRandomNumber(10); var guess; var guessCount = 0;

function getRandomNumber( upper ) { var num = Math.floor(Math.random() * upper) + 1; return num; } do{(guess = parseInt(prompt("Guess a number from 1 to 10"))); guessCount += 1; } while( guess!==randomNumber );

document.write ("You guessed the correct number of " + guess + ". " + " It took you " + guessCount + " tries to get the correct number.");
