Thank you!

Your code so far

1. The rating property is supposed to be named rating and not imdbRating

2. The final array is supposed to be assigned to the filteredList variable (change the map array name and use the filteredList name for the final filtered array instead).

thank you, I did change that but I am still getting an error, I think it is a parsing error

const filteredList = watchList.map(movies=>{
  return {
    Title: movies.Title,
    rating: movies.imdbRating
  }
});

filteredList.filter(movies=> movies.imdbRating >= 8.0)

You are still filtering on imdbRating and not rating.

Also, you need the array returned from the filter to be assigned to the filteredList variable.

edit: you also change the title property for some reason.

yes sorry, I went though multiple rounds of edit trying to get the same output that the excersise wants me to get so far this is what I have and I still do not know how to parse the rating number:

[ { Title: 'Inception', rating: '8.8' },
  { Title: 'Interstellar', rating: '8.6' },
  { Title: 'The Dark Knight', rating: '9.0' },
  { Title: 'Batman Begins', rating: '8.3' },
  { Title: 'Avatar', rating: '7.9' } ]

here is my latest stage and driving myself crazy now

const filteredList = watchList.map(movies=>{
  return {
    Title: movies.Title,
    rating: movies.imdbRating
  }
});

filteredList.filter(movies=> parseInt(movies.rating) >= 8.0)

The first error message I get is:

“Your code should use the filter method”.

You need to use filter and map together in the same statement. The method filter returns an array, so you can’t just call it on an array without saving the returned array. If you aren’t sure how to do this google “javascript method chaining”. Remember, the map method returns a new array and you can definitely use the filter method on any array.

Another issue is that you aren’t using the correct property name for title (capitalization matters).

@bbsmooth

thod returns a new array and you can definitely u

omfg! I can’t believe i just needed to chain the filter right after map without calling watchList again, thank you so much! Problem solved

const filteredList = watchList.map(movies=>{
  return {
    title: movies.Title,
    rating: movies.imdbRating
  }
}).filter(movies=> parseInt(movies.rating) >= 8.0)
