State & events

useState and useMemo work the way you expect from React, but Kog has no virtual DOM and no re-render. Each state change runs only the fine-grained effects that read that value, and each calls exactly one native setter. In the counter below, tapping +1 updates just the one label that reads count, nothing else.

onPress is a plain closure that always sees current state, with no dependency arrays and no stale captures.

Tap +1 and -1 in the simulator. This is the shipped examples/counter app, running on the same runtime it uses on a real board. It's imported here at build time, not copied.
