Hi Einar,

You cannot pass object property by reference. Using local array is the only way to pass array property to the function. The alternatives is to pass object reference and let function to acces any properties it needs. It could be object itself or some other object with array property.

* Pass reference to the object itself
f(this) 
* Pass reference to the object with array property
f(this.oAx)   && oAx is an object with Ax array property 

However in those cases your function should expect object not array as parameter.
