Test name	Executions per second
IF Logic	1258820.8 Ops/sec
Ternary Logic	1364584.5 Ops/sec

Script Preparation code:

var a = 10;
var b = 2;
var c = 0;

var curObj = {
  a : a,
  b : b,
  c : c
};
var nonZeroDivisorResult = 0;
var zeroDivisorResult = 0;

Tests:

IF Logic
if(b){ nonZeroDivisorResult = a/b; } else{ nonZeroDivisorResult = 0; } if(c){ zeroDivisorResult = a/c; } else{ zeroDivisorResult = 0; }
Ternary Logic
nonZeroDivisorResult = b ? a/b : 0; zeroDivisorResult = c ? a/c : 0;
AND Logic
nonZeroDivisorResult = b && a/b; zeroDivisorResult = c && a/c;
IF Logic with sloppy variable handling
if(curObj.b){ nonZeroDivisorResult = curObj.a/curObj.b; } else{ nonZeroDivisorResult = 0; } if(curObj.c){ zeroDivisorResult = curObj.a/curObj.c; } else{ zeroDivisorResult = 0; }
Ternary Logic with sloppy variable handling
nonZeroDivisorResult = curObj.b ? curObj.a/curObj.b : 0; zeroDivisorResult = curObj.c ? curObj.a/curObj.c : 0;
AND Logic with sloppy variable handling
nonZeroDivisorResult = curObj.b && curObj.a/curObj.b; zeroDivisorResult = curObj.c && curObj.a/curObj.c;
