The value attached to a node can be a set.

[{:app {:todos {:value #{}}}}]

This

[{:app {:todos #{}}}]

means that the child nodes of :todos will be stored in a set. Currently only maps and vectors are supported as containers of children. I have never actually used anything other than maps. Vectors are hard to deal with when mapping changes to the DOM because the keys are not stable.

That's the problem with vectors and trying to map changes to the dom with them. How does your use of maps perform?

Sorry, are you asking if maps as a container for children works fast enough? In practice I don't think we've seen any problems. I've honestly never used vectors as a container for children just because it is very hard to work with.
