Script Preparation code:

function getRandomNumberInRange(min = 0, max = 100) {
    return Math.floor(Math.random() * max) + min;
}

function getRandomValueInRange(min = 0, max = 100) {
    const range = max - min + 1;
    const randomBuffer = new Uint32Array(1);
    window.crypto.getRandomValues(randomBuffer);
    const randomNumber = randomBuffer[0];
    const scaledRandomNumber = Math.floor(
        randomNumber / (Math.pow(2, 32) / range)
    );
    return min + scaledRandomNumber;
}
