 React Compiler 是一个新的实验性编译器，我们已经将其开源，以便从社区中获得早期反馈。它是一个仅在构建时使用的工具，可以自动优化你的 React 应用程序。它可以与纯 JavaScript 一起使用，并且了解 [React 规则](/reference/rules)，因此你无需重写任何代码即可使用它。
 
 编译器还包括一个 [ESLint 插件](#installing-eslint-plugin-react-compiler)，可以在你的编辑器中直接显示编译器的分析结果。该插件独立运行，即使你的应用程序中没有使用编译器也可以使用。我们建议所有 React 开发人员使用这个 ESLint 插件来帮助提高代码库的质量。
+=======
+React Compiler is a new compiler currently in Beta, that we've open sourced to get early feedback from the community. While it has been used in production at companies like Meta, rolling out the compiler to production for your app will depend on the health of your codebase and how well you’ve followed the [Rules of React](/reference/rules).
+
+The latest Beta release can be found with the `@beta` tag, and daily experimental releases with `@experimental`.

+
+React Compiler is a new compiler that we've open sourced to get early feedback from the community. It is a build-time only tool that automatically optimizes your React app. It works with plain JavaScript, and understands the [Rules of React](/reference/rules), so you don't need to rewrite any code to use it.
+
+The compiler also includes an [eslint plugin](#installing-eslint-plugin-react-compiler) that surfaces the analysis from the compiler right in your editor. **We strongly recommend everyone use the linter today.** The linter does not require that you have the compiler installed, so you can use it even if you are not ready to try out the compiler.
+
+The compiler is currently released as `beta`, and is available to try out on React 17+ apps and libraries. To install the Beta:
+
+<TerminalBlock>
+npm install -D babel-plugin-react-compiler@beta eslint-plugin-react-compiler@beta
+</TerminalBlock>
+
+Or, if you're using Yarn:
+
+<TerminalBlock>
+yarn add -D babel-plugin-react-compiler@beta eslint-plugin-react-compiler@beta
+</TerminalBlock>
+
+If you are not using React 19 yet, please see [the section below](#using-react-compiler-with-react-17-or-18) for further instructions.

 ## 用法 {/*installation*/}
+=======
+### Using React Compiler with React 17 or 18 {/*using-react-compiler-with-react-17-or-18*/}
+
+React Compiler works best with React 19 RC. If you are unable to upgrade, you can install the extra `react-compiler-runtime` package which will allow the compiled code to run on versions prior to 19. However, note that the minimum supported version is 17.
+
+<TerminalBlock>
+npm install react-compiler-runtime@beta
+</TerminalBlock>
+
+You should also add the correct `target` to your compiler config, where `target` is the major version of React you are targeting:
+
+```js {3}
+// babel.config.js
+const ReactCompilerConfig = {
+  target: '18' // '17' | '18' | '19'
+};
+
+module.exports = function () {
+  return {
+    plugins: [
+      ['babel-plugin-react-compiler', ReactCompilerConfig],
+    ],
+  };
+};
+```
+
+### Using the compiler on libraries {/*using-the-compiler-on-libraries*/}
+
+React Compiler can also be used to compile libraries. Because React Compiler needs to run on the original source code prior to any code transformations, it is not possible for an application's build pipeline to compile the libraries they use. Hence, our recommendation is for library maintainers to independently compile and test their libraries with the compiler, and ship compiled code to npm.
+
+Because your code is pre-compiled, users of your library will not need to have the compiler enabled in order to benefit from the automatic memoization applied to your library. If your library targets apps not yet on React 19, specify a minimum [`target` and add `react-compiler-runtime` as a direct dependency](#using-react-compiler-with-react-17-or-18). The runtime package will use the correct implementation of APIs depending on the application's version, and polyfill the missing APIs if necessary.
+
+Library code can often require more complex patterns and usage of escape hatches. For this reason, we recommend ensuring that you have sufficient testing in order to identify any issues that might arise from using the compiler on your library. If you identify any issues, you can always opt-out the specific components or hooks with the [`'use no memo'` directive](#something-is-not-working-after-compilation).
+
+Similarly to apps, it is not necessary to fully compile 100% of your components or hooks to see benefits in your library. A good starting point might be to identify the most performance sensitive parts of your library and ensuring that they don't break the [Rules of React](/reference/rules), which you can use `eslint-plugin-react-compiler` to identify.

+=======
+React Compiler assumes that your code:
+
+1. Is valid, semantic JavaScript.
+2. Tests that nullable/optional values and properties are defined before accessing them (for example, by enabling [`strictNullChecks`](https://www.typescriptlang.org/tsconfig/#strictNullChecks) if using TypeScript), i.e., `if (object.nullableProperty) { object.nullableProperty.foo }` or with optional-chaining `object.nullableProperty?.foo`.
+3. Follows the [Rules of React](https://react.dev/reference/rules).
+
+React Compiler can verify many of the Rules of React statically, and will safely skip compilation when it detects an error. To see the errors we recommend also installing [eslint-plugin-react-compiler](https://www.npmjs.com/package/eslint-plugin-react-compiler).
