The getMilliseconds() method of Date instances returns the milliseconds for this date according to local time.
Syntax
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.
const xmas95 = new Date("1995-12-25T23:15:30");
const milliseconds = xmas95.getMilliseconds();
console.log(milliseconds); // 0
