javascript - Converting milliseconds while detecting single digit integers -

i created function detects , converts milliseconds minutes , seconds. i'd prepend 0 on either (or both) minute , second variables if number comes out less ten. instance if had integer 184213 evaluates 3:4 i'd 03:04. there short , concise way without having write out long conditional or ternary?

mstotime(184213);    function mstotime(milliseconds) {    var minutes = parseint(milliseconds/(1000*60)%60),        seconds = parseint((milliseconds/1000)%60);    return minutes + ':' + seconds;  }

a different approach utilizing date , slice:

function mstotime(milliseconds) {   var date = new date(milliseconds);   return date.totimestring().slice(3,8); }  mstotime(184213); // outputs: "03:04" 

a small caveat of course have limit of "23:59" , floor value milliseconds value on minutes not shown.
