-When a function contains `"use memo"`, the React Compiler will analyze and optimize it during build time. The compiler will automatically memoize values and components to prevent unnecessary re-computations and re-renders.
+当一个函数包含 `"use memo"` 指令时，React 编译器将在构建时对其进行分析和优化。编译器会自动对值和组件进行记忆化，以防止不必要的重计算和重渲染。
-#### Caveats {/*caveats*/}
+#### 注意事项 {/*caveats*/}
-* `"use memo"` must be at the very beginning of a function body, before any imports or other code (comments are OK).
-* The directive must be written with double or single quotes, not backticks.
-* The directive must exactly match `"use memo"`.
-* Only the first directive in a function is processed; additional directives are ignored.
-* The effect of the directive depends on your [`compilationMode`](/reference/react-compiler/compilationMode) setting.
+* `"use memo"` 必须位于函数体的最开始，在任何 import 语句或其他代码之前（注释除外）。
+* 该指令必须使用双引号或单引号，而不是反引号。
+* 该指令必须与 `"use memo"` 完全匹配。
+* 只有一个函数中的第一个指令会被处理；其余的指令将被忽略。
+* 指令的效果取决于你的 [`compilationMode`](/reference/react-compiler/compilationMode) 配置。
-### How `"use memo"` marks functions for optimization {/*how-use-memo-marks*/}
+### `"use memo"` 如何标记函数以进行优化 {/*how-use-memo-marks*/}
-In a React app that uses the React Compiler, functions are analyzed at build time to determine if they can be optimized. By default, the compiler automatically infers which components to memoize, but this can depend on your [`compilationMode`](/reference/react-compiler/compilationMode) setting if you've set it.
+在使用 React 编译器的应用中，所有函数都会在构建时被分析，以确定它们是否可以被优化。默认情况下，编译器会自动推断哪些组件需要被记忆化，但这取决于你所设置的 [`compilationMode`](/reference/react-compiler/compilationMode)。
-`"use memo"` explicitly marks a function for optimization, overriding the default behavior:
+`"use memo"` 可以显式地标记一个函数需要被优化，从而覆盖编译器的默认行为：
-* In `annotation` mode: Only functions with `"use memo"` are optimized
-* In `infer` mode: The compiler uses heuristics, but `"use memo"` forces optimization
-* In `all` mode: Everything is optimized by default, making `"use memo"` redundant
+* 在 `annotation` 模式下：只有带 `"use memo"` 的函数才会被优化
+* 在 `infer` 模式下：编译器使用启发式规则进行推断，但 `"use memo"` 会强制进行优化
+* 在 `all` 模式下：所有内容默认都会被优化，这使得 `"use memo"` 成为多余的
-The directive creates a clear boundary in your codebase between optimized and non-optimized code, giving you fine-grained control over the compilation process.
+该指令在你的代码库中为优化和非优化的代码创建了一个清晰的界限，让你能对编译过程进行精细化控制。
