Pick a random letter from string in JavaScript

Question

This question is different from Take random letters out from a string because I am not trying to remove anything from the string.

I\'m trying to pick a rand

Answer 1

Because you should obtain the letter every time, but you do it just once.

var emptyString = "";
var alphabet = "abcdefghijklmnopqrstuvwxyz";

while (emptyString.length < 6) {
  emptyString += alphabet[Math.floor(Math.random() * alphabet.length)];
} 
console.log(emptyString);

Also, not sure what you wanted to achieve with emptyString++, removing that, since ++ is the "increment by one" operator and you can't incremenent a string. I think the purpose was to have it as a counter for that while loop, but it's needless, since the counter is the string length already.
