Trying to fix my reduce function

[JeremyLT]

Hi,

In the solution, we have

@camperbot

    .reduce((sumOfRatings, rating) => sumOfRatings + rating) /
  watchList.filter(film => film.Director === "Christopher Nolan").length;

Notice that the division is outside of the reduce function. The average is (sum / length), but you were incrementally summing and dividing, which results in a very different calculation.

Edit, you can repair your accumulator function by only dividing the current value instead of the sum of the current value and the accumulator.
