Answer 1

• new Date() - creates a Date object representing the current date/time

• Date.now() - returns the number of milliseconds since midnight 01 January, 1970 UTC

As a matter of style, I found it clearer to use Date.now() in code that deals with intervals (usually subtracting an earlier date from a later date to calculate the time elapsed), and new Date() for timestamps, e.g. those written to a database.
