You have two objects:
const shoppingList = { milk: 1, bread: 2, sugar: 1};
const addingList = { apple: 4, lemon: 2 };Copy these two objects into another one using spread operator in order to get this:
const fullList = { milk: 1, bread: 2, sugar: 1, apple: 4, lemon: 2 }Tip: Do not console log the output. It's taken care of internally
