Test name	Executions per second
If and modulo array	549892.5 Ops/sec
Ternary and slice concatenation	628100.1 Ops/sec

Script Preparation code:

var z = 3661;
var t;

Tests:

If and modulo array
var y = []; if (z>3600){ y.push(Math.floor(z/3600)); } z%=3600; if (z>60){ y.push(Math.floor(z/60)); } z%=60; if (z>0){ y.push(Math.floor(z)); } t = y.join(":").replace(/\b(\d)\b/g,"0$1");
Ternary and slice concatenation
t = ("0"+Math.floor(z/3600).toString()).slice(-2)+":"+("0"+Math.floor(z%3600/60).toString()).slice(-2)+":"+("0"+Math.floor(z%3600%60).toString()).slice(-2)
