/*
  This function generates a random string of a given length. Useful when you need to generate a random string for a unique identifier or a password.
    @param {number} length - the length of the random string
    @returns {string} - returns a random string of the given length
    @example
    const randomString = generateRandomString(8);
    console.log(randomString); // Outputs a random string of length 8
