Tell us what’s happening:
Mind helping me figuring out why the code below doesn’t work?
Your code so far

// Only change code below this line

var filteredList = watchList
.map(({Title:title, ImdbRating:rating}) => ({title, rating}))
.filter(ref => ref.rating>=8.0);


// Only change code above this line

console.log(filteredList);

The code above returns and empty array. [ ]

code below works.

code below works.
var reference = watchList
.map(ref => ({
  title: ref.Title,
  rating: ref.imdbRating
}))

var filteredList = reference.filter(ref => ref.rating >= 8.0
)

Code below works too.

var filteredList = watchList
.map(ref =>{
  return{
    title: ref.Title,
    rating: ref.imdbRating
  }
})
.filter(ref => ref.rating>=8.0)

doing just this, the value of filteredList is:

[ { title: 'Inception', rating: undefined },
  { title: 'Interstellar', rating: undefined },
  { title: 'The Dark Knight', rating: undefined },
  { title: 'Batman Begins', rating: undefined },
  { title: 'Avatar', rating: undefined } ]

check really carefully for spelling errors
