What is the best way to initialize a JavaScript Date to midnight?

Question

What is the simplest way to obtain an instance of new Date() but set the time at midnight?

Answer 1

The setHours method can take optional minutes, seconds and ms arguments, for example:

var d = new Date();
d.setHours(0,0,0,0);

That will set the time to 00:00:00.000 of your current timezone, if you want to work in UTC time, you can use the setUTCHours method.
