如何删除Javascript数组中的重复对象属性

我和其他不同的用户之间有一个消息数组，我试图筛选该数组，使其只包含一个用户的单一事件（例如，在该数组中，我和John之间有10条消息，其中我是发送者或接收者），我试图获得一个只包含John的单一事件的新数组，最新消息（无论是约翰作为发送者还是接收者）。我和Jane之间也有两条消息（一条是我发送的，另一条是我接收的），我希望我和Jane之间也只有一条消息

最后，我试图得到一个包含三条消息的数组

-一个是托马斯

-一个是简

-一个是约翰

如果有人有解决方案，请分享

可能有不止一种方法可以做到这一点。在没有任何上下文的情况下，听起来好像您正在尝试在某些Javascript应用程序代码中执行此操作，假设这是解决问题的正确级别，我将这样做：

---

使用。对于每条消息，检查结果数组中的消息中是否已经存在另一条与该用户相关的消息。如果没有，则将消息添加到结果数组，否则返回结果数组。

您可以提取一个要对列表排序的不同键（名称） 用…然后排序

让dJson='{JSON}'
//获取所有发送方或接收方的名称作为密钥
let allNames=[]//所有邮件名称，包括dublicate
const p_me=JSON.parse（dJson）；
p_me['lol'].forEach（项目=>{
if（item.receiverInfo.name.toLowerCase（）！=“me”）{
allNames.push（item.receiverInfo.name.toLowerCase（））
}否则{
allNames.push（item.senderInfo.name.toLowerCase（））
}
})
//使用Set对象删除副本
让名称=[…新集合（所有名称）]；
//获取新的筛选列表
让MyList=[]//指定所需的列表
（姓名）{
对于（p_me的obj['lol']）{
if（obj.receiverInfo.name.toLowerCase（）==name | | obj.senderInfo.name.toLowerCase（）==name）{
//获取第一个匹配项，忽略相同名称的其他匹配项
MyList.push（obj）
打破
}
}
}

到目前为止，您尝试了什么？我尝试了数组集，我还尝试了循环和检查每个objectPost代码的实例，否则没有人知道您实际上在尝试做什么。
