问题是如何将JavaScript Date格式化为一个字符串，声明时间经过，类似于您在Stack Overflow上看到的时间显示方式。
e.g.
1分钟前 1小时前 1天前 1个月前 一年前

function timeSince(date) { var seconds = Math.floor((new Date() - date) / 1000); var interval = seconds / 31536000; if (interval > 1) { return Math.floor(interval) + " years"; } interval = seconds / 2592000; if (interval > 1) { return Math.floor(interval) + " months"; } interval = seconds / 86400; if (interval > 1) { return Math.floor(interval) + " days"; } interval = seconds / 3600; if (interval > 1) { return Math.floor(interval) + " hours"; } interval = seconds / 60; if (interval > 1) { return Math.floor(interval) + " minutes"; } return Math.floor(seconds) + " seconds"; } var aDay = 24*60*60*1000; console.log(timeSince(new Date(Date.now()-aDay))); console.log(timeSince(new Date(Date.now()-aDay*2)));

也可以使用dayjs的relativeTime插件来解决这个问题。
import * as dayjs from 'dayjs';
import * as relativeTime from 'dayjs/plugin/relativeTime';
dayjs.extend(relativeTime);
dayjs(dayjs('1990')).fromNow(); // x years ago
const createdAt = moment(created_at).fromNow()
量身定制的解决方案
const duration = moment.duration(moment().diff(moment(created_at)))
const createdAt = duration.as('week') >= 1
? `${Math.floor(duration.as('week'))} week(s)`
: duration.as('day') >= 1
? `${Math.floor(duration.as('day'))} day(s)`
: duration.as('hour') >= 1
? `${Math.floor(duration.as('hour'))} hour(s)`
: `${Math.floor(duration.as('minute'))} minute(s)`
我使用了可能11的旧答案，并添加了Intl。用于翻译的RelativeTimeFormat。
