this is my second contribution to the benchmarks :)

This one falls under #800. But it is also non-keyed so maybe no one cares.

Seems that is correct, view state is on the model. But I am actually not sure if this qualifies as keyed or non-keyed, since it internally uses a WeakMap to associate a model to a DOM node, so actually one could mess with the DOM externally and this would continue to work as expected.

That sounds like keyed then. If the data stays attached to the same DOM node for its lifetime. There is an isKeyed test.

@ryansolid thanks for the advice!

I did run the isKeyed test with npm run isKeyed -- --framework s2 and got:

s2-vinvalid (no package-lock)-keyed is keyed for 'run benchmark' and keyed for 'remove row benchmark' and keyed for 'swap rows benchmark' . It'll appear as keyed in the results

so it is indeed keyed.

Results are updated:

Nice to see that it turned out to be keyed. Performance looks pretty good!
