#1

its failing the last test even though am getting the right answer (8.675) can someone tell me what am doing wrong

function getRating(watchList) {
  // Only change code below this line
    let averageRating = watchList
    .filter(x => x.imdbRating > 7.9)
    .reduce((pre, cur) => pre + parseFloat(cur.imdbRating), 0) / 4;
  // Only change code above this line
  return averageRating; // 8.675 which is the right answer
}

console.log(getRating(watchList));

Where is this magic number coming from?

#3

so i can get the Average

#4

But it’s just a random 4. Why 4? You are hard cording which means that your function will break with any changes to the input.

#5

Also, is this the requirement in the challenge? I thought it was for movies directed by Christopher Nolan?

which means am going in the wrong direction right?

#7

You have some correct parts, you just need to make some fixes

  1. You need to filter movies for the director

  2. You need to compute the 4 instead of hardcoding the ‘magic number’
