[javascript-dev] Handling coll objects from inside js objects

Hello,
I had posted this question under "MaxMSP" section, so far got no answers, perhaps I may try to duplicate it in this section:

I am planning to implement a max prg which generates variational transformations on performer inputs (MIDI). For the manipulations and analyses to be made on the input sequence, I want to use javascript objects. Could anyone give me ideas or inform me about a method for how I can reference/handle the data structure in "coll"s using js code, within js objects at various parts of patches?

Thanks again.
