Info

Create an array of predefined length filled entirely with zeros.

Preparation code

<script>
// Final array will be 1,000,000 elements long

var i, arr,
    zeros = (function () {
        var i = Math.ceil(Math.random() * 1000),
            zs = []; 
        while (i--) zs.push(0);
        return zs
    })(),
    total_zeros = 1e6,
    num_zeros = total_zeros - zeros.length;

alert(num_zeros);

</script>
