我正在使用apollo's useQueryhook，我正在尋找一種更簡潔的方法來編寫以下語句 when datais undefined（或者甚至可以實現(xiàn)）。// hook example// const {data: {foo=[]}, loading} = useQuery(Q);const {data:{foo}, loading} = {data: {foo: [1, 2, 3, 4]}, loading: false};console.log(foo, loading);當(dāng)數(shù)據(jù)是undefined：// hook example// const {data:{}, loading} = useQuery(Q);// const {foo} = data;const {data={}, loading} = {data: undefined, loading: true};const {foo=[]} = data;console.log(foo, loading);謝謝你的幫助，
