What about the case where most products don’t have offerings, or the offerings don’t have merchants, vel cetera? If this were a frequent case, and this were inner-loop code, I might introduce a global empty object in order to reduce the object instantiation overhead (which happens right away) and the GC load (which shows up over time). E.g. define var $N={}, and use:
var product = ...,
merchantName = (((product||$N).offering||$N).merchant||$N).name;
if (merchantName)
displayMerchantName(merchantName);
$.extend({ myFunc : function(someArg, callbackFnk){ // do something here var data = 'test'; // now call a callback function if(typeof callbackFnk == 'function'){ callbackFnk.call(this, data); } } }); $.myFunc(someArg, function(arg){ // now my function is not hardcoded // in the plugin itself // and arg = 'test' });
