Hey all,
I'm working on a unit testing framework for unit testing javascript
abstractions that run in browsers: domunit.

The framework uses declarative style object literals for testing; each
test is property name that starts with

So thanks for the answer, and before flaming the next person,
consider that there are legitimate uses that you haven't thought of.

I have measured the speed of two sorts of Javascript trampolines,
which in both cases turned out to be about two orders of magnitude
slower than iterative code:

As for the setTimeout solution, yes it

There is also the sore spot of not being able to set the `toElement`

Is in your opinion better to create a DOM tree only once, clone it and then
traverse the clone only to update data, or to create everything by hand over
and over again?

Tests show that cloning is 38% better performer. What part of the code
would be the most likely culprit, the repeated calls to new Element or
something else?

The store will then send a notification event to the grid, which will
update the view to eliminate the row corresponding to the deleted item. This
follows proper MVC flow, with the controller affecting the model, which then
affects the view.
In MVC pattern, MODEL don't communicate with VIEW,

There is some problem with these tests, as it throws some error in Opera 11.
And the error is somewhat strange, at least i haven't seen such (although
i've never used MooTools either).
Error: java.lang.NoSuchFieldException: getAttribute in class: nano.

The technical ideas are fine, but I do not agree that they are the
solution. And actually, in this case, pulling everything into one
large global function will result in a one big function.
Doing that just transfers the ball of mud from being global to being
namespaced. No benefit is
Hmmm,
how this work in practice? The model will have a callback function? The
model will refresh the view? Who will trigger the action to refresh the
