javascript - javascript变量/函数的首字母是什么意思

Question

下面的代码只是一个示例，该代码来自 jQuery DataTable。 我只是想知道oTable中的“o”，bServerSide中的“b”等的含义是什么。它们有某种意义吗？

  var oTable = $('#unis').dataTable({
    //"bProcessing": true,
    "bServerSide": true,
    "sAjaxSource": "index.php?...&<?php echo JSession::getFormToken() . '=1' ?>",
    "sDom": "<'row-fluid'<'span6'T><'span6'f>r>t<'row-fluid'<'span6'l><'span6'p>>",
    "sPaginationType": "bootstrap",
       "aoColumns":[
                {"bSortable": false},
                {"bSortable": false},
                {"bSortable": true},
                {"bSortable": true},
                {"bSortable": false},
              ],
    "oTableTools": {
    "aButtons": [ "delete selected", "export" ]
}  

});

看起来像Systems Hungarian notation :

In Systems Hungarian notation, the prefix encodes the actual data type of the variable.

bServerSide -> b -> bool  
sAjaxSource -> s -> string  
oTableTools -> o -> object  
aButtons    -> a -> array
