React Children 재귀 순회

WARNING

가능하지만 비추천 - 암묵적 의존성, 타입 안전성 부족, 매 렌더 트리 순회, 예측 불가능

function traverseReactNode(children: ReactNode, callback, typeToMatch?) {
  Children.forEach(children, (child) => {
    if (!isValidElement(child)) return
    if (child.type === Fragment) {
      traverseReactNode(child.props.children, callback, typeToMatch)
      return
    }
    if (child.type === typeToMatch) callback(child)
    if (child.props?.children) {
      traverseReactNode(child.props.children, callback, typeToMatch)
    }
  })
}

대안 - Compound Component

<Tabs.Root>
  <Tabs.List>
    <Tabs.Trigger value="a">A</Tabs.Trigger>
  </Tabs.List>
  <Tabs.Content value="a">Content</Tabs.Content>
</Tabs.Root>
