How do you display JavaScript datetime in 12 hour AM/PM format?

Question

How do you display a JavaScript datetime object in the 12 hour format (AM/PM)?

Answer 1

If you don't need to print the am/pm, I found the following nice and concise:

var now = new Date();
var hours = now.getHours() % 12 || 12;  // 12h instead of 24h, with 12 instead of 0.
