I have books data. I'd like to return the books if they match the author's id. When I try to filter out data that does not match my 'author's' id. However, it always returns all book data.
const author = "AUTHOR#e9bb9d29-7f20-4fce-892c-6a155dbee42c";
const Book = [

const Books = Book.filter((i) => {
console.log(i.GSI1SK);
i.GSI1SK === author;
return i;
});
console.log(Books);You are using filter the wrong way, you should return true or false based on the condition you're matching,
const Books = Book.filter((i) => {
console.log(i.GSI1SK);
return i.GSI1SK === author;
});
And you can omit unnecessary lines. Try this.
const Books = Book.filter(i => i.GSI1SK === author)
