On: How I built a fast JavaScript framework

This isn't necessarily true. In fact, it's not true of Surplus and Radi.js, which is partly why they're much faster than every vdom framework out there.

[amelius → naasking]

They're faster because they are not computing DOM (or vdom) nodes when that's not needed.

But they're creating new DOM nodes when values-on-which-the-code-depends change.
