JavaScript Date now() Method

JavaScript date.now() method is used to return the number of milliseconds elapsed since January 1, 1970, 00:00:00 UTC. Since now() is a static method of Date, it will always be used as Date.now().

let A = Date.now();

Parameters: This method does not accept any parameter. 

Return Values: It returns the number of milliseconds elapsed since January 1, 1970, 00:00:00 UTC.
