You could have done this part as well with a for loop, like this:

function averageWordLength(array) {
  if (array.length === 0) {
    return undefined;
  }
  var sumLetters = 0;
  for (var i = 0; i < array.length; i++) {
    sumLetters += array[i].length;
  }
  return sumLetters / array.length;
}

It was a good beginning. With a for loop, you would probably have done it till the end.
Here is the solution to do it with a for loop. Don't be afraid of it! ;)

function uniquifyArray(array) {
  var newArray = [];
  if (array.length === 0) {
    return undefined;
  }
  for (var i = 0; i < array.length; i++) {
    if (newArray.indexOf(array[i]) === -1) {
      newArray.push(array[i]);
    }
  }
  return newArray;
}

Well done! You understood the notions in the exercise. Keep going this way!
