title: fs.statSync throws error if file does not exist
body: <p>I am attempting to determine if a file exists. If it does not exist, I would like my code to continue so it will be created. When I use the following code, if the file exists, it prints that 'it exists'. If it does not exist, it crashes my app. Here is my code:</p>
  
  <pre><code>var checkDuplicateFile = function(){
      var number = room.number.toString();
      var stats = fs.statSync(number);
      if(stat){
          console.log('it exists');
      }else{
          console.log('it does not exist');
      }
  
  };
  </code></pre>
