How to generate 4 random numbers between 1-10 and have one declared a winner (Javascript)

I'm trying to create a random number generator. so far I have

<script>
   var arr = []
  while (arr.length < 4) {
    var randomnum = Math.ceil(Math.random() * 10)
    var found = false;
    for (var i = 0; i < arr.length; i++) {
      if (arr[i] == randomnum) {
        found = true;
        break
      }
    }
    if (!found) arr[arr.length] = randomnum;
  }
  document.write(arr);     
</script>

But instead of having the numbers display in line, i'd like to have it say "person a rolls __, Person b rolls __, etc" but I have no idea how to do that through javascript.

Also, how would I declare a winner, like "Person A Wins" (the winner being the highest roller)

Thanks in advance.
