The Date.prototype.toLocaleTimeString() method returns a string with a language sensitive representation of the time portion of this date. It is available for modern browsers.

Unfortunately, the native function is not able to prevent the output of seconds. By default, it outputs a time format like hh:mm:ss or hh:mm AM/PM etc.

second: The representation of the second. Possible values are numeric, 2-digit.

This means, that you can not use something like {second: false}.

I'm looking for a simple stupid solution, to remove the seconds from a hh:mm:ss formatted string.

var date = new Date();

var time = date.toLocaleTimeString(navigator.language, {hour: '2-digit', minute:'2-digit'});

console.log(time); // 15:24:07

This regular expressions don't work:

time.replace(/:dd( |$)/,'');

time.replace(/(d{2}:d{2})(?::d{2})?(?:am|pm)?/);
