javascript multidimensional Array and associative array
<p>i am new of javascript, i have been told by someone, he said "speak strictly, javascript doesn't have  multidimensional Array and associative array ". but in a book, i saw the following </p>

<pre><code>var my_cars=Array();
my_cars["cool"]="Mustang";

$a=Array(Array(0,1),2);
</code></pre>

<p>so the opinion form  he is wrong? am i right?</p>
