Can't resolve challenge

[datnt1997]

Tell us what’s happening:
I also follow the hint but can’t resolve this challenge.

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"]);

Sort an Array Alphabetically using the sort Method not working still

I assume you’re using Chrome? The example given (using a < b to sort in reverse alphabetical order) is not correct afaics. Removing the callback should sort in the correct order by default: it sorts by character code points, and a comes before b, b comes before c, etc. But for the callback, it should return -1 (or a negative number), 0, or 1 (or a positive number). So b - a, not a > b (which returns true or false instead)

Look at how Array.sort() works.

• If compareFunction(a, b) is less than 0, sort a to an index lower than b , i.e. a comes first.
• If compareFunction(a, b) returns 0, leave a and b unchanged with respect to each other, but sorted with respect to all different elements. Note: the ECMAscript standard does not guarantee this behaviour, and thus not all browsers (e.g. Mozilla versions dating back to at least 2003) respect this.
• If compareFunction(a, b) is greater than 0, sort b to an index lower than a , i.e. b comes first.
