Followed the coding with the video and it seems I followed Dave pretty well, But when I test the program and guess correctly (example) it tells me sorry the number was 5. Even if i guessed 5. Can someone tell me what I am missing.
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 ) {
correctGuess = true;
} else if (parseInt(guess) > randomNumber) {
var guessLess = prompt('Try Again. The number I am thinking of is less than '+ guess);
if (parseInt(guessLess) === randomNumber){
guessLess = true;
}
} else if (parseInt(guess) < randomNumber) {
var guessMore = prompt('Try Again. The number I am thinking of is More than ' + guess);
if (parseInt(guessMore) === randomNumber) {
guessMore = true;
}
}
if ( correctGuess ) {
document.write('<p>You guessed the number!</p>');
} else {
document.write('<p>Sorry. The number was ' + randomNumber + '.</p>');
}

Fix the issue by changing each assignment to set "correctGuess".

if ( correctGuess ) {only checks whether correctGuess is true. It doesn't check guessLess or guessMore. So even if they are set to true, your final conditional isn't testing them, it's only testing correctGuess, which is set to false at the top of your program.Since
if ( correctGuess ) {is only testing correctGuess, it will always return false until correctGuess is re-set to true. So your sorry message will always print. (Unless you guess the number correct on your first try, which sets correctGuess here:if (parseInt(guess) === randomNumber ) { correctGuess = true;and will causeif ( correctGuess ) {to print your victory message.So, you either need to test for guessMore and guessLess in your final conditional:
if ( correctGuess || guessMore || guessLess)or you need to change bothguessLess = true;andguessMore = true;tocorrectGuess = true.In the first case, you are testing whether any of guessMore, guessLess or correctGuess is true, so if any one of them is true, even if the other two are false, the statement will evaluate to true and your victory message will print.
In the second case, you set correctGuess to true when either
parseInt(guessMore) === randomNumberorparseInt(guessLess) === randomNumber). Since correctGuess is now set to true, your final conditional will pass and your victory message will print.
