Issues with transform exercise on Windows

[marcinwasilewski]

I tried to run the official solution for transforms exercise which in my case should look as follows:

  var fs = require('fs');                                                                                                                           
  var txt = fs.readFileSync('C:\Users\marcin\AppData\Roaming\npm\node_modules\browserify-adventure\problems\using_transforms\wake.txt', 'utf8');    
  var sprintf = require('sprintf');                                                                                                                 
                                                                                                                                                    
  var lines = txt.split('\n');                                                                                                                      
  lines.forEach(function (line, index) {                                                                                                            
      if (index % 5 === 0) {                                                                                                                        
          console.log(sprintf('%3d %s', index, line));                                                                                              
      }                                                                                                                                             
      else {                                                                                                                                        
          console.log('    ' + line);                                                                                                               
      }                                                                                                                                             
  });       

That however produces a SyntaxError:

For some reason saving the file wake.txt to a local directory and changing the path to relative in readFileSync solves the issue.

var txt = fs.readFileSync('wake.txt', 'utf8');
