        "books": books.map( book => ({"name": book.name)) )

use the map operator to iterate each element from books array

const books = [
            {
                "name": "John Adventure",
                "year": 2021,
                "author": "John doe",
            },
            {
                "name": "Marry Adventure",
                "year": 2021,
                "author": "Marry doe",
            },
            {
                "name": "Steven Adventure",
                "year": 2021,
                "author": "Steven doe",
            }
        ];
        
let result = {
  status: "success",
  data: {}
};
result.data.books =  books.map(item => { return {"name":item.name}}); 
console.log(result);
