It is not exactly the same but it is faster.

Microbenchmark:

<html>
<script type="text/javascript">
var a = 0;

var d=new Date();
for(var x = 0; x < 10000000; x++) {
    if (!a){}
}
var e = new Date() -d;
var f=new Date();
for(var b = 0; b < 10000000; b++) {
    if (a==0){}
}
var g = new Date() -d;
alert(e);
alert(g);
</script>
</html>
