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?

You could use patcher scripting methods to set and retrieve data 

remotely, but that's not the same as accessing the data structure 

And since you're in javascript already, why not use the much more 

powerful data structures possible in this language?

See the Maxobj section in JavascriptingMax.pdf.

An easy way would be to be to give your [coll ] instance a name (let 

say "mySuperColl_hider"), define in your js file a loadbang function 

    myColl = this.patcher.getnamed("mySuperColl_hider");

If you need to get values, you may have a look at this thread:

I know Jeremy B. compiled a [js] version with a get function, but I 

dont know wether it has made its way to a public release...

In Max5, things may have changes, but I couldn't find any serious

function loadbang ()

	myColl.message (...);
	...
}

In Max5, things may have changes, but I couldn't find any serious  
documentation yet.

Considering your advices, it seems easier not to get involved in 'coll's but staying more in js arrays from the start.
