That’s a good q @erosman but I never bothered because if there is a lower performance to use jsonToDOM (which I doubt) the strengths far outweigh it. Templating is absolute cake with jsonToDOM.
Only weakness of jsonToDOM is that it doesnt handle attaching multiple listneres to a specific event. Like for example, you can only add one listener to onclick, as the object is a key value pair, i was thinking of improving it, doing a test on the on* things, and if its an array then it attaches them all.
