    Navigator.productSub

    Non-standard
    This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

    The Navigator.productSub read-only property returns the build number of the current browser.

    • prodSub is a string.

    <script> 
    function prodsub() {
      var dt = document.getElementById("d").childNodes[0];
      dt.data = window.navigator.productSub;
    } 
    </script>
    
    <button onclick="prodsub();">productSub</button>
    // returns: 20010725
