Actually, me and phiggins were looking at TaskSpeed bench and he spotted an
error in my Pure DOM which was basically the reason we realized every single
test there was wrong.
let's do an example. My document has 3 divs:
'<div><div></div></div><div></div>'
one is nested ... now I do this:
$("div").html("leak?").length; // which is 3
I am not sure if all libraries are managing the case in the same way but I
would not leave that div wrapped in that variable.
If jQuery object related search is saved, it could be useful to re-search it
after each operation otherwise problems like this will be truly common and
leaks more probable than pure DOM manipulation.
That test for example is now:
var div = document.getElementsByTagName("div"), i = 0;
while(div[i])
div[i++].innerHTML = "leak?";
return i;
because getElementsByTagName is live and I do not want to trap anything.
Makes sense?
