kuito.
Loslegen

provide

Called while a component sets up: its descendants inherit value for key. A signal (a computed too) is what they read: a write reaches the bindings that read it, and nothing re-renders.

Funktion

Verwendung

tsx
import { Text, VStack, inherit, inherited, provide, signal } from 'kuito';
