Benchmark: Local scope vs outer scope variables

Script Preparation code:

var testVar = 10;

Tests:

Cache in the inner scope
function doTest1(){ var sum = 0; for (var i = 0; i < testVar; i++){ sum = sum + i; } } doTest1();
Do not cache at all
function doTest2(){ var sum = 0; var testVarLocal = testVar; for (var i = 0; i < testVarLocal; i++){ sum = sum + i; } } doTest2();
