How to add multiple divs with appendChild?

Question

I am trying to make a chessboard using javascript and creating 64 divs with it.
The problem is, that it creates only the first div.
Here is the code:

Answer 1

function crt_dv(){
dv=document.createElement('div'),document.body.appendChild(dv)
};

crt_dv(),dv.className='white';crt_dv(),dv.className='black';

Also use: for(i=0;i<2;i++)
