How to show only hours and minutes from javascript date.toLocaleTimeString()?

Here is a more general version of this question, which covers locales other than en-US. Also, there can be issues parsing the output from toLocaleTimeString(), so CJLopez suggests using this instead:

var dateWithouthSecond = new Date();
dateWithouthSecond.toLocaleTimeString(navigator.language, {hour: '2-digit', minute:'2-digit'});
