# Why do we we need to define correctGuess?

If a boolean is inherently true or false, why do we have to define correctGuess ?Can't we just say if (guess === true)?

The variable "guess" is not a boolean, and holds the answer given by the user (a string), so it could not be used that way.

But, you do have the right idea in that "correctGuess" could be eliminated by using only the first "if" (that compares the input to the random number) to control the outputs directly.

I suspect the extra step is being used to illustrate the boolean nature of the comparison being made, but that could also be done more directly with an assignment (and no conditional):

```var correctGuess = parseInt(guess) == randomNumber;
```

Just remember that the code examples you see are provided to illustrate the concepts being introduced, and will not necessarily be examples of the most efficient way to accomplish a specific task.

well, i think we need to compare guess with the Correct guess to find out if its really true or not! if we just say

```if(guess === true){}
```

it means that if there is actually a guess (aside from it's being true or not) but we don't know if its really the true answer or not because we don't have any meter for that. by defining correctGuess we actually have our meter to check the correct of not correct answer .

happy coding ;)

Thanks guys, that makes sense. I think it was confusing to me by using a variable called "correctGuess" I was running on the assumption it took a user input first. It's also very early here in California and I may not be fully awake yet. Thanks for the quick responses!

Jennifer Ciaccio — Glad to help. You can mark a question solved by choosing a "best answer".

Happy coding!

```JavaScript
do {
var correctGuess = false;
var randomNumber = Math.floor(Math.random() * 6 ) + 1;
var guess = prompt('I am thinking of a number between 1 and 6. What is it?');
if (parseInt(guess) === randomNumber ) {
document.write('<p>You guessed the number!</p>');
correctGuess = true;
} else {
alert('Sorry. The number was ' + randomNumber+'.');
var playAgain = prompt('Do you want to try your luck again? Enter "Y" to play again or "N" to stop.' );
if (playAgain.toUpperCase() === "N") {
correctGuess = true;
}
}
}
while (!correctGuess);```
