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

You need to change getRandomLetter into a function, and reassign randomLetter inside the loop like this:

var emptyString = "";
var alphabet = "abcdefghijklmnopqrstuvwxyz";
function getRandomLetter() {
  return alphabet[Math.floor(Math.random() * alphabet.length)];
}
var randomLetter;

while (emptyString.length < 6) {
  randomLetter = getRandomLetter();
  emptyString += randomLetter;
} 
console.log(emptyString);

You also can't increment emptyString, since it is a string.
