Why does this print statement have commas in it?

JavaScript
1

So I wrote:

function reverseString(str) {
  var str2 = []; 
  for (var i=0; i<str.length; i++) {
    str2.unshift(str[i]); 
  } 
  str2.join(""); 
  str = str2.toString();
  console.log(str);  
  return str;
}

reverseString("hello");

I thought str2.join("") got rid of the commas.

It does, but it returns a string. I don’t see where you are capturing this returned string.

Then how come when I print out str2 it prints out an array?

you are not capturing the returned string, join returns a string, but you are not doing anything with the returned value
