Mithril is roughly equal in scope to Knockout+Sammy. The small gap between what most frameworks call "bidirectional data binding" and what it actually is in terms of vanilla js can be bridged with simple functions (I talk about that in a slightly more advanced context here: http://lhorie.github.io/mithril-blog/asymmetrical-data-bindings.html http://lhorie.github.io/mithril-blog/asymmetrical-data-bindi... ). Dependency tracking can refer to two things: tracking changes for the purpose of updating the DOM (which Mithril does handle, albeit in a different way), or computed properties (which I personally think are not a good idea, but that you could do w/ an observable library from microjs)
