Please copy/paste all the editor code showing in the challenge from where you just linked.

function getRating(watchList) {
  // Only change code below this line
  let averageRating = watchList
  .filter(movie => movie.imdbRating >= 8.0)
  .map(movie =>({title: movie["Title"], rating: movie["imdbRating"], director: movie["Director"]}));

  // Only change code above this line
  return averageRating = watchList.reduce((sum, movie) => sum + movie.imdbRating / averageRating.length, 0);
}

console.log(getRating(watchList));

Use reduce to find the average IMDB rating of the movies directed by Christopher Nolan .

I don’t think your filter does what its supposed to.

that was a loop hole i figured out all movie’s are directed but avatar and avatar has a imdbRating of 7.9 So i figured i can get isolate that out

But that’s not the same thing as finding all Nolan films. That won’t work for all tests.
