Jonas,

It looks to me you are mixing up objects and arrays.

The below website shows the usage of arrays withoud using actual objects or 
functions for it:

https://eloquentjavascript.net/04_data.html

This one shows what I call an /object/ (as in: having properties and/or 
methods) and how to store varaibles and array into it.

https://stackoverflow.com/questions/14652504/performance-using-array-in-the-object-namespace-vs-local-array

Also, your "function newCollection(m)" returns a pointer to the function 
itself(?), not to the array you created -which will be discarded (it 
disappears) as soon as you leave that function.  In other words: you should 
be using "return extSynth();".

But that creates its own problem, as you will than return the /whole/ array 
(with all the "objects" in it), not just the one you just created.

Yeah, it looks like you mixed up a few things there.  Have you ever tried to 
access (read, write, read - in that order) that returned object ?   And ? 
What happened ? :-)
