How to use new Date().valueOf() method In Javascript

This method returns the primitive value of a Date object, which is the number of milliseconds since January 1, 1970, 00:00:00 UTC.

Syntax:

let timestamp = new Date().valueOf();

Example: In this example, new Date().valueOf() creates a new Date object and retrieves its timestamp in milliseconds. The timestamp variable holds this value, which is then logged to the console.

Javascript
const timestamp = new Date().valueOf();
console.log(timestamp);

Output
1704969022368
