Date.prototype.getMilliseconds()
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The getMilliseconds() method of Date instances returns the milliseconds for this date according to local time.
Try it
const moonLanding = new Date("July 20, 69 00:20:18");
moonLanding.setMilliseconds(123);
console.log(moonLanding.getMilliseconds());
// Expected output: 123
Syntax
js
getMilliseconds()
Parameters
None.
Return value
An integer, between 0 and 999, representing the milliseconds for the given date according to local time. Returns NaN if the date is invalid.
Examples
Using getMilliseconds()
The milliseconds variable has value 0, based on the value of the Date object xmas95, which doesn't specify the milliseconds component, so it defaults to 0.
js
const xmas95 = new Date("1995-12-25T23:15:30");
const milliseconds = xmas95.getMilliseconds();
console.log(milliseconds); // 0
