Access whole list.A nested for loop

Running into performance problems I think... is interesting. why is it only going so fast?

My nested for loop indexes over the entire list. How would artificial intelligence be able to do this working with matrixies would be tough inside a nested for loop every time.

you would have to update the parameters of the matrix. Something matlab, and octave, and sci.py do well. The language Julia(I wish that was taught here) is as fast a C and it uses matrix operators.

var playList = [
  ['I Did It My Way', 'Frank Sinatra','2p','4'],
  ['Respect', 'Aretha Franklin','2','5'],
  ['Imagine', 'John Lennon','6','7'],
  ['Born to Run', 'Bruce Springsteen','8','9'],
  ['Louie Louie', 'The Kingsmen',11,77], 
  ['Maybellene', 'Chuck Berry',77,66]
];

function print(message) {
  document.write(message);
}

function printSongs( songs ) {
  var listHTML = '<ol>';
  var j = 0;
  for ( var i = 0; i < songs.length; i += 1) {
    //listHTML += '<li>' + songs[i][j] + '</li>';
    for ( j = 0; j < songs[i].length; j += 1){
      listHTML += '<li>' + songs[i][j] + '</li>';
    }
  }
  listHTML += '</ol>';
  print(listHTML);
}

printSongs(playList);

I'm not sure what you are asking about. Can you explain your question or what you specifically need help with?
