You're debugging a piece of code that is returning an array in an unexpected order after a sort() method is applied. What could be a likely cause for this behavior given the default behavior of sort()?

  • The array has mixed data types
  • The sort() function is asynchronous
  • The array elements are all numbers
  • The array elements are strings
JavaScript's sort() method by default converts elements to strings and then compares their UTF-16 code units. This means that if the array contains mixed data types, the sorting order might be unexpected. For proper sorting, you should provide a compare function as an argument to sort().
