-React and [Web Components](https://developer.mozilla.org/en-US/docs/Web/Web_Components) are built to solve different problems.  Web Components provide strong encapsulation for reusable components, while React provides a declarative library that keeps the DOM in sync with your data. The two goals are complementary. As a developer, you are free to use React in your Web Components, or to use Web Components in React, or both.
+React 和 [Web Components](https://developer.mozilla.org/en-US/docs/Web/Web_Components) 为了解决不同的问题而生。Web Components 为可复用组件提供了强大的封装，而 React 则提供了声明式的解决方案，使 DOM 与数据保持同步。两者旨在互补。作为开发人员，可以自由选择在 Web Components 中使用 React，或者在 React 中使用 Web Components，或者两者共存。
 
-Most people who use React don't use Web Components, but you may want to, especially if you are using third-party UI components that are written using Web Components.
+大多数开发者在使用 React 时，不使用 Web Components，但可能你会需要使用，尤其是在使用 Web Components 编写的第三方 UI 组件时。

-> Web Components often expose an imperative API. For instance, a `video` Web Component might expose `play()` and `pause()` functions. To access the imperative APIs of a Web Component, you will need to use a ref to interact with the DOM node directly. If you are using third-party Web Components, the best solution is to write a React component that behaves as a wrapper for your Web Component.
+> Web Components 通常暴露的是命令式 API。例如，Web Components 的组件 `video` 可能会公开 `play()` 和 `pause()` 方法。要访问 Web Components 的命令式 API，你需要使用 `ref` 直接与 DOM 节点进行交互。如果你使用的是第三方 Web Components，那么最好的解决方案是编写 React 组件包装该 Web Components。

-> Events emitted by a Web Component may not properly propagate through a React render tree.
-> You will need to manually attach event handlers to handle these events within your React components.
+> Web Components 触发的事件可能无法通过 React 渲染树正确的传递。
+> 你需要在 React 组件中手动添加事件处理器来处理这些事件。
 
-One common confusion is that Web Components use "class" instead of "className".
+常见的误区是在 Web Components 中使用的是 `class` 而非 `className`。
