Re: Browser Memory Leaks

Garbage collection can only collect those objects which are not referenced from _anywhere_.

I thought I read somewhere that setting a value to null (in JavaScript) would allow memory to be reclaimed. But I'm less certain about arrays, where you might set its length to 0.

If setting the length to zero does not clear out the objects in the array you have these invisible references that are just a pain to find.

This is a frequent issue in Java too, where you cannot explicitly
tell an object to go away forever.

I think I got the problem under control by explicitly evoking the DOM removeEventListener() and removeChild() methods. But I'm going to keep an eye on it.
Good luck and have fun :)
