document.deleteElement()?

Question

For some reason, I create a temporal HTML element using document.createElement(). The element is not appended to the document tree. I make a new element every mousemove(). Does that allocate any type of memory that I need to deallocate when I am done with the element? How?

If you don't add the element to the DOM or keep any other references to it, they will be freed by the garbage collector. There's no need to manually destroy them.
