Reversing a string using an ArrayBuffer

How many more ways are there to reverse a string in JavaScript? I was reading the friendly manual again and thought of another way.

The method is let down a little by the .map() at the end. I was rather hoping for a less pedestrian way of changing the ArrayBuffer back into normal text.

The other gotcha is that we're storing uint values, so prepare for mangled emojis.

function Bruce_ByteBuffer(string) {
  let buffer = new ArrayBuffer(string.length);
  let int8View = new Uint8Array(buffer);
  for (let i = 0, j = string.length - 1; i < string.length; i++, j--) {
    int8View[i] = string.charCodeAt(j);
  }
  return Array.prototype.slice.call(int8View).map(function (item) {
    return String.fromCharCode(item)
  }).join("");
}

Speed-wise, using my framework, it's in the slower end of midrange.
