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

我一直在寻找这个问题的答案，并且几乎实现了其中一个解决方案，但一位同事提醒我检查react-intl库，因为我们已经在使用它了。
所以在解决方案中…在使用react-intl库的情况下，它们有一个<FormattedRelative>组件。

在这种情况下可能有点过头了，但如果有机会，moment.js真的很棒!
js是一个javascript datetime库，在这种情况下使用它，你需要做:
moment(yourdate).fromNow()

2018附录:Luxon是一个新的现代图书馆，可能值得一看!
2022年附录:Day.js是一个较新的库，比Luxon轻80%左右，具有类似的功能。
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
我的解决方案。
(function(global){
const SECOND = 1;
const MINUTE = 60;
const HOUR = 3600;
const DAY = 86400;
const MONTH = 2629746;
const YEAR = 31556952;
const DECADE = 315569520;
global.timeAgo = function(date){
var now = new Date();
var diff = Math.round(( now - date ) / 1000);
var unit = '';
var num = 0;
var plural = false;
switch(true){
case diff <= 0:
return 'just now';
break;
case diff < MINUTE:
num = Math.round(diff / SECOND);
unit = 'sec';
plural = num > 1;
break;
case diff < HOUR:
num = Math.round(diff / MINUTE);
unit = 'min';
plural = num > 1;
break;
case diff < DAY:
num = Math.round(diff / HOUR);
unit = 'hour';
plural = num > 1;
break;
case diff < MONTH:
num = Math.round(diff / DAY);
unit = 'day';
plural = num > 1;
break;
case diff < YEAR:
num = Math.round(diff / MONTH);
unit = 'month';
plural = num > 1;
break;
case diff < DECADE:
num = Math.round(diff / YEAR);
unit = 'year';
plural = num > 1;
break;
default:
num = Math.round(diff / YEAR);
unit = 'year';
plural = num > 1;
}
var str = '';
if(num){
str += `${num} `;
}
str += `${unit}`;
if(plural){
str += 's';
}
str += ' ago';
return str;
}
})(window);
console.log(timeAgo(new Date()));
console.log(timeAgo(new Date('Jun 03 2018 15:12:19 GMT+0300 (FLE Daylight Time)')));
console.log(timeAgo(new Date('Jun 03 2018 13:12:19 GMT+0300 (FLE Daylight Time)')));
console.log(timeAgo(new Date('May 28 2018 13:12:19 GMT+0300 (FLE Daylight Time)')));
console.log(timeAgo(new Date('May 28 2017 13:12:19 GMT+0300 (FLE Daylight Time)')));
console.log(timeAgo(new Date('May 28 2000 13:12:19 GMT+0300 (FLE Daylight Time)')));
console.log(timeAgo(new Date('Sep 10 1994 13:12:19 GMT+0300 (FLE Daylight Time)')));
const timeHandler = (time: any) => {
var a = moment(); //now
var b = moment.utc(time);
const sec = a.diff(b, 'seconds');
const minuts = a.diff(b, 'minutes');
const hours = a.diff(b, 'hours');
const days = a.diff(b, 'days');
const weeks = a.diff(b, 'weeks');
return weeks == 0
? days == 0
? hours == 0
? minuts == 0
? sec >= 0 && `${sec}s ago`
: `${minuts}m ago`
: `${hours}h ago`
: `${days}d ago`
: `${weeks}w ago`;
};
console.log(timeHandler('2022-11-11T12:11:06.6103808'))
