ivi VS blockdom

ivi, Preact, and more

And the answer was: it depends. The Virtual DOM library I tested, ivi, had no issues handling more components. But Lit and Svelte were dramatically worse. They scaled back to almost React levels of performance as I broke them down to more components. All their non-VDOM performance benefits basically disappeared.

Some things are just inherently complex. Look at virtual dom reconciliation algorithm, for example. Others simply don't benefit from overly aggressive pursuit of "improvements". Look at database levels of normalization for another example of how one can apply theoretical "best practices" to the wazoo and completely lose sight of pragmatism.

blockdom (Géry Debongnie) Thank you to Géry pioneering the concept of "blocks" in the virtual DOM. Many parts of the Million.js codebase either directly or indirectly derive from his work.

this is 100% false, look at the js framework benchmark and u'll see that vanilla-js with DOM is faster than any other framework and almost twice as fast as react. not that VDOM is slow its just that react's implementation is slow. blockdom for example uses VDOM and its very close to vanilla's performance

If you've been around in the JavaScript UI library development space, you've likely heard about blockdom, which claims to be probably the fastest Virtual DOM that currently exists.
