Questions for you.
1) Are they just marked for deletion for later garbage collection?
1. I have been told to set unused stuff to null or delete unused fields prior to returning back to system as this will aid in JS Garbage collection. I have not dug into the implementation of Spidermonkey to say for sure. However, more objects, as noted does slow this down. It is likely the latter and not the former that you should be worried about.
2) On page exit, do the dynamic objects get destroyed anyway.....in which case I don't have to clean up saving a few cycles or is it more efficient the way I'm doing it
2a. As good practice, you should always clean up your variables.
2b. Javascript scoping rules enforce that at page exit, any variables that were declared via the page script are wiped and a GC cycle will occur. This includes both the page object scope and dynamic widgets for the page as well as any functions added to them. (See 2a).
