Get random number with JavaScript

In PHP the rand() function returns a random number between a given minimum and maximum (by default 0 and 32767). The whole looks like this:

<?php
  $randomNumber = rand(1,100); // random number between 1 and 100
  echo $randomNumber;
?>

The same function can be rebuild with JavaScript:

<script type="text/javascript">
  function rand(min,max){
    if (arguments.length === 0){
      min = 0;
      max = 32767;
    }
    return Math.floor(Math.random() * (max - min + 1)) + min;
  }
 
  var randomNumber = rand(1,100); // random number between 1 and 100
  document.write(randomNumber);
</script>
