javascript how to create reference

Question

Could you propose any workarounds to implement a reference to variable using closures or any other tricks?

createReference = function() {
    // TODO: how to         


        

Answer 1

Since objects will always be a static reference, you can do this:

var o = {};
o.x = 5;
var oRef = o;
alert(oRef.x); // -> 5
o.x = 6;
alert(oRef.x); // -> 6
