Do innerHTML create nodes in the DOM tree?

[mwm]

If I do this:\[code\]document.getElementById("myDiv").innerHTML = "some_html_code";\[/code\]will that create nodes in my DOM three as it would if I used \[code\]appendChild()\[/code\]?Reason for asking is that I'm creating a mobile application where memory usage must be low. I don't want to create a lot of garbage when later emptying the same div.
