Let's see how we can detect the Operating System on which the website is accessed using Javascript.

Sample Code:

<a>Host:</a>
<a id="detectos"></a>
<script> 
        HTMLDocument.prototype.e = document.getElementById; 
        var exdo = document.e("detectos"); 
        var Name = "Not known"; 
        if (navigator.platform.indexOf('Win32', 'Win64', 'Windows', 'WinCE') != -1) Name =  
          "Windows"; 
        if (navigator.platform.indexOf('Macintosh', 'MacIntel', 'MacPPC', 'Mac68K') != -1) Name =  
          "macOS"; 
        if (navigator.appVersion.indexOf("X11") != -1) Name =  
          "UNIX"; 
        if (navigator.appVersion.indexOf("Linux") != -1) Name =  
          "Linux";
        if (navigator.platform.indexOf('iPhone','iPod') != -1) Name =  
          "iOS";
         if (navigator.platform.indexOf('iPad') != -1) Name =  
          "iPadOS";
        exdo.innerHTML = Name; 
</script>

Output:

Here, detectos is the id given to the string where the output will be displayed. exdo is simply a variable assigned to the id.
