I want to calculate date difference in days, hours, minutes, seconds, milliseconds, nanoseconds, how can I do it? Please suggest.

推荐答案

假设你有两个 日期对象，您可以减去它们以获得毫秒的差异：

Assuming you have two Date objects, you can just subtract them to get the difference in milliseconds:

var difference = date2 - date1;

从那里，您可以使用简单的算术来获取其他值。

From there, you can use simple arithmetic to derive the other values.
