鑒于這兩個(gè)數(shù)組：var amounts = [9, 1, 8, 16, 5, 1, 42]var animals = ["ducks", "elephants", "pangolins", "zebras", "giraffes", "penguins", "llamas"]我必須編寫一個(gè)函數(shù)，它接受兩個(gè)變量并返回一個(gè)組合字符串。預(yù)期的輸出是："9 ducks 1 elephants 8 pangolins 16 zebras 5 giraffes 1 penguins 42 llamas"我創(chuàng)建了一個(gè)類似于預(yù)期字符串的對象。我現(xiàn)在需要按該順序打印屬性。function animalsAmounts(arr1, arr2){    let object = {};    arr2.forEach((arr2, i) => object[arr2] = arr1[i]);    return object    let result = Object.keys(object).map(function(key) {        return [Number(key), obj[key]];    }); return result}console.log(animalsAmounts(amounts, animals))它打?。簕 ducks: 9,  elephants: 1,  pangolins: 8,  zebras: 16,  giraffes: 5,  penguins: 1,  llamas: 42 }我不知道如何將預(yù)期結(jié)果作為字符串返回。我嘗試了各種方法來記錄數(shù)量和動(dòng)物，但只能返回一種或另一種。
