构建一个返回满足约束

Question

我一直在使用数据集并解决了一些限制，但现在我被卡住了。

非常感谢任何帮助和解释。

问题是：

编写接受活动日志文件的绝对路径的函数bot_spammers，并返回所有垃圾邮件发送者名称的列表

识别垃圾邮件的条件是：

- The user has no original tweets.
- The user has at least one retweet.
- All the retweets of this user occur within 1000 milliseconds of the original tweet.
- In the corner case where the retweet occurs exactly 1000 milliseconds after the original tweet, it should also be considered as a spam retweet.

- The output list must not contain duplicates.

到目前为止，这是我的解决方案：

let dataEntry = data.trim().split('\n').map(dataLog=>{
          return JSON.parse(dataLog);
        });

dataEntry[0];
let users = {};
let secondOutput = []

for(let i = 0; i < dataEntry.length;i++){
  if(!users[dataEntry[i].user]){
      users[dataEntry[i].user] = {
        actions:{
          [dataEntry[i].action]:0},
          bot:false};
  } else{
   users[dataEntry[i].user].actions[dataEntry[i].action]+=1;
  }
}

目前我的用户对象在第一次看到用户时会存储用户，但我也会收到推文作为NaN。我存储用户错了吗？

此处还有我正在使用的示例数据：
