[JavaScript] Generate Random String From [a-z0-9]

/**
 * Returns a random integer between min (inclusive) and max (inclusive)
 * Using Math.round() will give you a non-uniform distribution!
 * Code from http://stackoverflow.com/a/1527820
 */
function getRandomInt(min, max) {
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

/**
 * Input: the length of random string
 * Output: a random string from [a-z0-9]
 */
function RandomString(strlen) {
    const chars = "abcdefghijklmnopqrstuvwxyz0123456789";
    var result = "";
    for (var i=0; i<strlen; i++) {
        result += chars[getRandomInt(0,35)];
    }
    return result;
}

// function call to generate a random string of length 10
RandomString(10);
