Arrays in Javascript
<p>I always had this silly doubt in mind but never had come up with the solution.</p>

<p>I have seen several kind of arrays but I don't know the difference between them. I don't know how to explain exactly but it's most when passing parameters with jQuery.</p>

<p>See:</p>

<p><code>{ 'choices[]': ["Jon", "Susan"] }</code> in <code>$("#objectID").load("test.php", { 'choices[]': ["Jon", "Susan"] } );</code></p>

<p>What's the {}? (does this mean it's an array?). Why is <code>choices[]</code> quoted? I have already seen unquoted ones, what's the difference? I presume that <code>choices</code> is the associative name and <code>["Jon", "Susan"]</code>  is the value, is it right?</p>
