Kaedah untuk mendapatkan pasangan nilai kunci tertentu dalam objek tatasusunan


records = [{id: 231, first_name: "Jack", last_name: "Aston", email: "jack55@xyz.com"}, {id: 232, first_name: "Roy", last_name: "Dillon", email: "roy@xy.com"}, {id: 233, first_name: "Jacy", last_name: "Wilson", email: "jacy@x.com"}]

fields = ['id', 'email', 'last_name']

Bagaimana untuk mendapatkan hanya "id", "emel" dan "last_name" daripada rekod supaya data kelihatan seperti ini dalam JavaScript?

new_records = [{id: 231, email: "jack55@xyz.com", last_name: "Aston"}, {id: 232, email: "roy@xy.com", last_name: "Dillon"}, {id: 233, email: "jacy@x.com", last_name: "Wilson"}]
