Improving the Random Number Guessing Game

So with this game that we revised the code, it is basically using else/if to do this.

It will prompt the user to put a number in, it takes it in as the string and converts to a number.

If the number you guessed is more or less than what the random number it will execute the else statement at the bottom.

If it is true then it will say that you guessed right what the random number was.

Am i getting this right? Also, are we changing the value of correctGuess from false to true?

Code:

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 guessMore = prompt('Try again. The number i am think of is more than ' + guess);

if (parseInt(guessMore === randomNumber)) {

correctGuess = true;

}

} else if ( parseInt(guess) > randomNumber ) {

var guessLess = prompt('Try again. The number i am think of is more than ' + guess); }

if (parseInt(guessLess === randomNumber)) {

correctGuess = true;

}

if ( correctGuess ) { document.write('<p>You guessed the number!</p>'); } else { document.write('<p>Sorry. The number was ' + randomNumber + '.</p>'); }

Yes

Also, why don't you put your code like this:

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 guessMore = prompt("Try again. The number I am thinking of is more than " + guess);
  if (parseInt(guessMore) === 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) {
      correctGuess = true;
}

if ( correctGuess ) {
    document.write('<p>You guessed the number!</p>');
} else {
    document.write('<p>Sorry. The number was ' + randomNumber + '.</p>');
}
