I'm currently completing an assignment where I need to pass the following test

* should work on an arguments object

Here is my code.

function first (array, n) {
  var result = [];
  if (Array.isArray(array)) {
    if (n && n > 0) {
      var number = n > array.length ? array.length : n;
      for (var i=0; i < number; i++) {
        result.push(array[i]);
      }
    } else {
      result.push(array[0]);
    }
    return result;
  } else {
    return result;
  }
};

Im not sure what lines I need to ammend to make it pass this test, can anyone help me?
