I think I was testing scope performance rather than closure performance at that time. Hi Xavier,

Scope of function withClosure() is document's root which means a global scope and not a specific scope kept in memory. I think a closure test should seams like that : function withClosure () { var i = 0; var count = 1000000; var num = 0; function incClosure() { num++; } while (i++ < count) incClosure(); } Hi,

function withClosure () {
var i = 0;
var count = 1000000;
var num = 0;
function incClosure() {
num++;
}
while (i++ < count) incClosure();
}
