Your code so far
Hey all…this challenge seems to be easy and i cant find my mistake…kindly someone to tell me whats wrong with my code. Thanks.

function alphabeticalOrder(arr) {
  // Only change code below this line
  return arr.sort(function(a, b){
    return a - b;
  });
  // Only change code above this line
}

console.log(alphabeticalOrder(["a", "d", "c", "a", "z", "g"]));

Can you explain why you decided to use this code here?

(Does subtracting letters help to sort them?)

The thing about sort is all it really cares about with its callback is if the value it returns is 0, less than 0 (-1), or greater then zero (1), and based on that it will move the items in a or b to there appropriate spots. Here you are using the minus (-) with a and b, and a and b are strings. What is 'a'-'b' going to get you in Javascript? The other example code is more what you want, but it can look very confusing if your new to coding with its two ternary operators.

4

Why not take a look and see what the sort method does by default?

5

To return the strings in an ascending order

6

Do you still believe that subtracting letters will help to sort them though? (Or have you had a chance to rethink that?)
