Can I trigger JavaScript's garbage collection?

Question

I want to trigger JavaScript garbage collection. Is it possible? Why would I want to, or not want to, do this?

Answer 1

You can trigger manually JavaScript garbage collector in IE and Opera, but it's not recommended, so better don't use it at all. I give commands more just for information purpose.

Internet Explorer:

window.CollectGarbage()

Opera 7+:

window.opera.collect()
