Is JQuery $.post() asynchronous? : <p>Is $.post asynchronous?  So if I did the commands like so below would they all be done at once instead of being synchronous (1 done, wait, then the next, etc.) ?</p>

<pre><code>$(document).ready(function() {
    var variable1 = '1';
    var variable2 = '2';
    var variable3 = '3';
    var variable4 = '4';

    $.post("process.php", {element1: variable1}, function(data){
        $("#area1").html(data);
    });

    $.post("process.php", {element2: variable2}, function(data){
        $("#area3").html(data);
    });

    $.post("process.php", {element3: variable3}, function(data){
        $("#area4").html(data);
    });

    $.post("process.php", {element4: variable4}, function(data){
        $("#area4").html(data);
    });
});
</code></pre>
