Re: Browser Memory Leaks

From: Thorbjørn Ravn Andersen
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.

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.

Nathan.
