someModule.js

buildData: function () {
  var newData, data = api.getSongs();
  
  // Fix paths
  var transformPath = this.transformPath.bind(this);

  newData = data.map(function (row) {
      row.path = transformSongPath(row.path);
      return row;
  });
  
  this.data = newData;
},
transformPath: function (path) {
  // ... some simple string transformations ...
}

Looking for ways to refactor this. How can I make this look nicer and simpler?
