-浏览器使用许多树形结构来为 UI 建立模型。[DOM](https://developer.mozilla.org/docs/Web/API/Document_Object_Model/Introduction) 用于表示 HTML 元素，[CSSOM](https://developer.mozilla.org/docs/Web/API/CSS_Object_Model) 则表示 CSS 元素。甚至还有 [Accessibility tree](https://developer.mozilla.org/docs/Glossary/Accessibility_tree)！
-
-React 也使用树形结构来对你创造的 UI 进行管理和建模。React 根据你的 JSX 生成 **UI 树**。React DOM 根据 UI 树去更新浏览器的 DOM 元素。（React Native 则将这些 UI 树转译成移动平台上特有的元素。）

The middle section contains a tree of components, with the root labeled 'A' and two children labeled 'B' and 'C'. The next section is again transitioned using an arrow with the React logo on top labeled 'React'. The third and final section is a wireframe of a browser, containing a tree of 8 nodes, which has only a subset highlighted (indicating the subtree from the middle section).">

-当你为一个组件添加 state 时，你可能会觉得 state “活”在组件内部。但实际上，state 被保存在 React 内部。根据组件在 UI 树中的位置，React 将它所持有的每个 state 与正确的组件关联起来。

 When you give a component state, you might think the state "lives" inside the component. But the state is actually held inside React. React associates each piece of state it's holding with the correct component by where that component sits in the render tree.
