所以我在這里有這個(gè)測(cè)試虛擬數(shù)據(jù)：{    _id: "1",    name: "Lakawon Island Resort",    price_per_night: 2804.0,    description:      "On a lush 16-hectare island with white-sand beaches, this relaxed resort is 5 km from the jetty in Cadiz Viejo, a village on the mainland.",    address: "Cadiz Viejo",    city: "New York",    state: "New York",    zip_code: "6121",    latitude: 11.045411,    longitude: 123.201465,    phone: "(034) 213 6354",    email: "info@example.com",    website: 'www.lakawonislandresort.us',    amenities:       {        tv: false,        reservation: false,        cabin: true,        services: true,    },    image:      "https://images.unsplash.com/photo-1512356181113-853a150f1aa7",    rating: 4.5,    reviews: 11,  },請(qǐng)注意，我有這個(gè)對(duì)象amenities，它也是一個(gè)對(duì)象。目前我有 4 個(gè)子對(duì)象tv，reservation和cabin。services我需要的是檢查每個(gè)項(xiàng)目是否為真，如果它們確實(shí)為真，則返回對(duì)象的鍵并在其旁邊添加一個(gè)超棒的字體圖標(biāo)。否則，如果該值為 false，則不執(zhí)行任何操作或返回 null。到目前為止，這是我的實(shí)現(xiàn)方式：{amenities && Object.entries(amenities).map(    ([key, value]) => {        if(key === 'tv' && key[value] === true){            return `<p><i class="fa fa-tv"></i>  ${key}</p>`        } else if (key === 'reservation' && key[value] === true){            return `<p><i class="fa fa-reservation"></i>  ${key}</p>`        }else if (key === 'cabin' && key[value] === true){            return `<p><i class="fa fa-cabin"></i>  ${key}</p>`        }else if (key === 'services' && key[value] === true){            return `<p><i class="fa fa-service"></i>  ${key}</p>`        }               return null    })}但是，這不起作用，而是返回錯(cuò)誤Can't map through object。知道如何檢查每個(gè)鍵是否為真，然后如果值為真，則在其旁邊輸出各自的 fontawesome 圖標(biāo)？有沒(méi)有比 if else 語(yǔ)句更有效的方法來(lái)做到這一點(diǎn)？
