JavaScript
1

Tell us what’s happening:
Is that true? Please help me.

Your code so far


function alphabeticalOrder(arr) {
  // Add your code below this line
  return arr.sort(function(a,b) {
    return a > b;
  });
  
  // Add your code above this line
}
alphabeticalOrder(["a", "d", "c", "a", "z", "g"]);

A more compact way is to use the arrow function:

const alphabeticalOrder = arr => arr.sort((a,b) => a > b)

No. There is an error in this challenge (which has been fixed, but the update isn’t ready for release yet).
return a > b will work in Firefox because Firefox decided to implement the sort function in a non-standard way.
