javascript - 如何将两个对象列表合并为 1 个对象列表，同时合并对象

Question

标题听起来可能比实际情况更复杂。

我有 2 个数组，由两个不同的映射创建。然后我继续像这样遍历每个数组:

let temp = [];
    let temp2 = [];

    nameArray.forEach(function(x){
        temp.push({question: x[0]})
    })
    bodyArray.forEach(function(x){
        temp2.push({answer: x[0]})
    })

给我结果:

[0:{question: "generic question"}
 1:{question:...}
 2:{...}]

和:

[0:{answer: "generic answer"}
 1:{answer:...}
 2:{...}]

我最终想要得到的是单个对象列表，并且对象是来自两个数组的对象，但像这样合并:

[0:{question: "generic question", answer: "generic answer"}]

Answer 1

您可以使用 array#map 并遍历您的问题数组，通过使用 question 数组的索引，您可以从您的 answer 添加元素> 数组并生成包含问题和答案的对象数组。

const questions = ["generic question", "generic question 12", "generic question 34"],
      answers = ["generic answer", "generic answer 12", "generic answer 34"];

const merged = questions.map((question, i) => ({question, 'answer' : answers[i]}));
console.log(merged);
