Javascript 获取数据并向Json对象添加标题

我想为我的JSON对象添加标题，我希望实现的结构是：

{
"posts": [
    {
        "title": "put title here",
        "upvotes": 1234,
        "score": 1000,
        "num_comments": 100,
        "created": "16.05.2019 12:12",
    },
]
}

我能够获取数据并将其放入26个元素的数组中，一切都很好，但我希望以某种方式添加“posts:”以超越整个rest，以下是我的代码：

fetch("https://www.reddit.com/r/funny.json")
.then(resp => resp.json()
.then(async res => {
   let posts = await res.data.children.map(el => {
    let title = el.data.title;
    let upvote = el.data.ups;
    let score = el.data.score;
    let comments = el.data.num_comments;
    let created = el.data.created;
    const allPosts = {title, upvote, score, comments, created}
    postList.push(allPosts)
    return postList
})  
console.log(posts);

    return posts    
})

您可能需要创建如下所示的对象

{propertyName:value}

您可以尝试以下代码

fetch（“https://www.reddit.com/r/funny.json")
.then（resp=>resp.json（））
。然后（res=>({
posts:res.data.children.map（el=>({
标题：el.data.title，
upvote:el.data.upvote，
分数：el.data.score，
注释：el.data.num_注释，
创建：el.data.created
}))
}))
。然后（posts=>{
控制台日志（posts）；
});您可以尝试以下代码


fetch（“https://www.reddit.com/r/funny.json")
.then（resp=>resp.json（））
。然后（res=>({
posts:res.data.children.map（el=>({
标题：el.data.title，
upvote:el.data.upvote，
分数：el.data.score，
注释：el.data.num_注释，
创建：el.data.created
}))
}))
。然后（posts=>{
控制台日志（posts）；
});您可以这样做：

fetch("https://www.reddit.com/r/funny.json")
    .then(resp => resp.json()
        .then(async res => {
            let posts = await res.data.children.map(el => {
                return {
                    title: el.data.title,
                    upvote: el.data.ups,
                    score: el.data.score,
                    comments: el.data.num_comments,
                    created: el.data.created
                }
            })
            const postObject = { posts }
            console.log(postObject);
            return postObject
        })

映射函数返回值，通过这种方式可以得到一个带有键（posts）和值（带有细节的对象）的对象。

            })
            const postObject = { posts }
            console.log(postObject);
            return postObject
        })

Map函数返回值，通过这种方式可以得到一个包含键（posts）和值（包含细节的对象）的对象

  fetch("https://www.reddit.com/r/funny.json")
  .then(resp => resp.json())
  .then(async res => {
    console.log(res);
    let posts = await res.data.children.map(el => {
      let title = el.data.title;
      let upvote = el.data.ups;
      let score = el.data.score;
      let comments = el.data.num_comments;
      let created = el.data.created;
      const allPosts = { title, upvote, score, comments, created };
      let postList = [];
      postList.push(allPosts);
      return postList;
    });
    console.log({"posts": posts});

    return {"posts": posts};
  });
