How to get the current timestamp in JS

1、var timestamp =Date.parse(new Date());

The result obtained: 1657876666000 Note: The result obtained here converts the last three digits (milliseconds) into 000 for display

2、var timestamp =(new Date()).valueOf();

Result: 1657876666

3、var timestamp=new Date().getTime()；

Result: 1657876666

Call new Date() separately in js, such as console.log(new Date());

The displayed result is: Mar 31 10:10:43 UTC+0800 2012 The time in this format

But using new Date() to participate in the calculation will automatically convert to the number of milliseconds since 1970.1.1.
