如何在react native中显示html响应并将日期显示为Today，Yesterday ..in react native

Question

在这里，我有一个带有3个值的“活动”数组。我正在映射该值并显示在下面。但是我必须显示created_at是今天的日期，如果它的最后一天是昨天，则应该在下面的标签上显示今天，昨天和其余所有都应显示相同的值，例如“ 2019-07-09”。  我也可以获取今天的日期和昨天的日期，但在我看来无法显示。其次，我的消息响应来自html标签，我该如何更改它并在我的本机视图中显示。请帮忙。

let today =new(Date);
let Yesterday=new Date(today);
Yesterday.setDate(today.getDate() - 1);

 const { navigation,isLoading,notifications } = this.props;
  active: Array(3)
    0:
    created_at: "2019-07-09T14:38:44.442Z"
    expires_at: "2019-12-29T00:00:00.000Z"
    message: "<p>Long notification test&nbsp;Long notification test&nbsp;Long notification test Long notification test&nbsp;Long notification test&nbsp;Long notification test&nbsp;Long notification test&nbsp;Long notification test</p>"
    status: 1
    title: "Long notification test again"
    __typename: "NotificationList"
    _id: "5a4653746e8fe500370fd744"

    1:
    created_at: "2019-02-25T12:42:02.966Z"
    expires_at: "2020-05-31T00:00:00.000Z"
    message: "<p>Hi Hello</p>"
    status: 1
    title: "Hi Hello"
    __typename: "NotificationList"
    _id: "5c73e29a77939a0036af7631"

    2:
    created_at: "2018-07-10T13:29:45.713Z"
    expires_at: "2019-12-25T00:00:00.000Z"
    message: "<p>This is testing annoucement</p>"
    status: 1
    title: "testing annoucement"
    __typename: "NotificationList"
    _id: "5a5cacc9a67c2c004befb146"

{notifications.notificationList.active.map((data,index) =>{
           return(
             <View key={index}>
              <View style={{flexDirection:'column', backgroundColor:'white'}}>
                <Label text= {`${data.created_at}`}/>
                <Heading title={`${data.title}`} time="9.00 am"/>
                <Content text={`${data.message}`}/>
              </View>
            </View>
           )
           })}

谢谢
