Generate a random string from given characters

const generateString = (length, chars) =>
    Array(length)
        .fill('')
        .map((v) => chars[Math.floor(Math.random() * chars.length)])
        .join('');

const generateString = (length: number, chars: string) =>
    Array(length)
        .fill('')
        .map((v) => chars[Math.floor(Math.random() * chars.length)])
        .join('');

generateString(10, '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ');
