Listings 13.05 and 13.06 - Using the Number Generator in the guessing game - Task 3

Update the game so that it keeps track of the number of guesses a player takes to find the secret number.

var getGuesser = function (lowest, highest) {
    var secret = between(lowest, highest);
    var numGuesses = 0;

    return function (userNumber) {
        numGuesses += 1;

        if (userNumber === secret) {
            return "Well done! You took " + numGuesses + " guesses.";
        } else if (userNumber > secret) {
            return "Too high!";
        } else {
            return "Too low!";
        }
    };
};

var guess = getGuesser(5, 10);
