Program dengan Javascript

Buatlah program dengan javascript untuk alur seperti berikut :

<script language="javascript">
var a=12;
var b=4;
function pd2(b) {
var a=b*2;
return a; }
document.write("Dua kali dari ",b," adalah ",pd2(b));
document.write(" Nilai dari a adalah", a);
</script>

Dari kode script di atas, maka hasilkalinya adalah....?

Tara...



Masih berhubungan dengan kode program pada nomor sebelumnya, apabila kode program pada baris ke 5 var a=b*2; diganti dengan a=b*2;

Maka hasilnya adalah ??

Berapa Ya???? udah tau jawabannya???

Ini dia..
