Update the second condition to (userNumber < secret)
Update the messages to match the new condition.

var getGuesser = function () {
    var secret = Math.floor(Math.random() * 10 + 1);

    return function (userNumber) {
        if (userNumber === secret) {
            return "Well done!";
        } else {
            if (userNumber < secret) {

            } else {
                return "Too high!";
            }

Listing 12.05 - Higher or Lower - Tasks 5 & 6

Swap the first and second conditions so the second condition uses the strict equality operator.
Update the messages to match the new condition.

var getGuesser = function () {
    var secret = Math.floor(Math.random() * 10 + 1);

    return function (userNumber) {
        if (userNumber < secret) {
            return "Too low!";
        } else {
            if (userNumber === secret) {
                return "Well done!";
            } else {
                return "Too high!";
            }
        }
    };
