javascript - DataTables initialization keywords different with official examples -

i'm new datatables due new requirements of project. i've started learn it, i'm confused inconsistency between official site examples , real usages.

specifically, wonder why name of options when initialize datatables different between official examples , practical use. example, in official guides, initializing table static data demonstrated follow:

$('#example').datatable( {     data: data } ); 

however, after realised not work. searched in statckoverflow got solution should be

$('#example').datatable({     "aadata": data }); 

so, why maintain gap. because of issues namespace? also, if different, how know correct keywords of options?

i know question might stupid, failed find answer many hours. appreciated.

hungarian notation aadata used jquery datatables 1.9. new camelcase naming convention data used in jquery datatables 1.10+. both supported in jquery datatables 1.10+ provide backward compatibility.

see converting parameter names 1.10 more information.

documentation older 1.9 version still available @ http://legacy.datatables.net/
