title: nodejs fs mode manipulation in windows read-only attribute
body: <p>I am new to NodeJS and I'm having a hard time decrypting the mode value and figuring out how to change the mode to remove an attribute like read-only. Here is how I found this folder to have a mode of 16822. How do I determine what 16822 means in windows and then how do I change mode so that it does not have a read only attr? </p>
  
  <pre><code>fs.mkdir('./build');
  fs.stat('./build', function(err, stats){
     if(stats.isDirectory()){
         console.log('Its a dir');
  
         for(var i in stats){
             if('function' !== typeof stats[i]){
                 console.log(i + '\t= ' + stats[i]);
             }
         }
     }
  });
  </code></pre>
