Removing DOM nodes in JavaScript to save memory

Question

I use the Safari browser to view my web page, which is rich in Javascript. I see that Safari takes up a lot of memory (500-900 MB) when browsing a web page and performing various operations. I want to know if I need to delete DOM objects using, for example var elem = document.getElementById('Id1');, to optimize the use of this memory? If any other pointers please suggest. Also, how can we remove this DOM object in the easiest way?

Thanks Siddhart

, :

elem.parentNode.removeChild(elem);
