Hello!

I found on "wtfjs.com" a method to do JS-reference, as the & in php.

MAYBE this can improve JS.

This is the basic idea:

1. function x(object){
2.   // I need re-use object on another method
3.   reUse(object); // I suppose that JS copy object to reUse function
4.   console.log(object);
5.   // Here is different, JS will pass a reference of object, but it's strange...
6.   reUseAgain(arguments);
7.   console.log(object);
8. }
9.  
10. function reUse(object){
11.   object = 1;
12. }
13.  
14. function reUseAgain(object){
15.   object[0] = 1;
16. }
17.  
18. x(0);
19. // log: 0 (without reference)
20. // log: 1 (with reference)

Or be, jQuery probably (I don't know) copy too many times objects. With arguments method this can be changed. But it will really improve speed?

I cannot do this test with certain, if an expert can do, then show to us! :)

Bye.
