如何获取JavaScript中两个日期之间的天数？例如,在输入框中给出两个日期:

<input id="first" value="1/1/2000"/>
<input id="second" value="1/1/2001"/>

<script>
  alert(datediff("day", first, second)); // what goes here?
</script>

I work with moment.js and I have 3 different dates, e.g.

• 30.07.2018
• 12.06.2018
• 10.05.2018

I now try to get the difference in days from these dates until today (if it is less then 7 days ago) or the weeks until today (if it more than 7 days ago) and place it in several spans.

UPDATE thanks Thomas!

I got:

$(document).ready(function(){
    $('.timestamp').html((index, html) => {

        let date = moment(html, "DD.MM.YYYY HH:mm", true), 
        now = moment(),
        days = Math.floor(Math.abs(date - now) / …
