JavaScript: Faster way to create and initialize two dimensional array (matrix)
<p>Is there a faster way to create and zero out a matrix?<br />
Currently, my code involves two for loops:</p>

<pre><code>var nodes = new Array(ast.length);

for (var i=0; i &lt; nodes.length; i++){
    nodes[i] = new Array(ast.length);
    for (var j=0; j &lt; nodes.length; j++)
        nodes[i][j]=0;
}
</code></pre>
