I am using this function to build a pig latin translator and seem to have everything figured out except for the .trim() part. What should I do different?

function ParseText() 

{



  var  myText = asdfn hatn cat dogn apple;



  var lines = myText.split(n);

  var results = ;



  for (var i = 0, len = lines.length; i < len; i++) {

    lines[i].trim();

    var words = lines[i].split( );



    for (var j = 0, lenght = words.length; j < lenght; j++) {

      var word = words[j];



      if (word.charAt(0) == a || word.charAt(0) == e ||  word.charAt(0) == i || word.charAt(0) == o || word.charAt(0) == u || word.charAt(0) == y)



      {

        results = results + word + ay ;

      }else {

        var mutated = word.substring(1, word.length);

        mutated = mutated + word.charAt(0)+ ay ;

        results = results + mutated;

      }

    }

    results = results + n;

  }

  return results;

}

On the line lines[i].trim(); nothing seems to happen. the whitespace still becomes a n item in the split array.

What should I change to remove the whitespace?
