This code works in other editors, but not in FCC.
Why?


  function reverseString(str) {

      let arr = [];
      arr = str.split('');
      arr.reverse();
      str = arr.join();

      return str;
    }

reverseString("hello");

Not quiet. Commas are added between letters like this.

'o,l,l,e,h'

Hint: You need pass a parameter inside your join method.

Right! Sorry I missed that. Thanks for the comment.
