Reverse a String why?

Tell us what’s happening:
i don’t undestand what is the problem, when i test the code on console i received the right answer

function reverseString(str) {
return str.split(’’).reverse();

(5) [“o”, “l”, “l”, “e”, “h”]

Your code so far

function reverseString(str) {
  return str.split('').reverse();

Link to the challenge:

You are returning an array instead of a string.

the answer expects olleh but you returned (5) [“o”, “l”, “l”, “e”, “h”]
