Say you have the following array:
let characters = ['ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz', '1234567890', '!@#$%^&*()'];
Would it be possible to get a random string, from any index? Say I wanted at least 1 string value from index 0. Could I loop through the array, and grab the random letter from index 0? What would that look like?
