jquery - defining local variables using an object in javascript -

may silly question, wanted know if there's difference (performance wise) between following.

someobject.prototype.myfunc = function() {  var = 123;  var b = "something";  ... }     someobject.prototype.myfunc = function() {  var loc = {};  loc.a = 123;  loc.b = "something";  ... }    

i've been doing second way, been easier debug doing console.log(loc) , it's habit doing server side code i've been defining local structures.

as per tests done phil (http://jsperf.com/direct-variable-vs-object-property-assignment) there's noticeable difference between using direct variable assignment , object property assignment.

definitely using direct variable assignment
