-*Hooks* are a new addition in React 16.8. They let you use state and other React features without writing a class.
+*Hook* 是 React 16.8 的新增特性。它可以让你在不使用 class 的情况下使用 state 和一些其他 React 特性。
 
-Hooks are JavaScript functions, but you need to follow two rules when using them. We provide a [linter plugin](https://www.npmjs.com/package/eslint-plugin-react-hooks) to enforce these rules automatically:
+Hook 本质就是 JavaScript 函数，但是在使用它时需要遵循两条规则。我们提供了一个 [linter 插件](https://www.npmjs.com/package/eslint-plugin-react-hooks)来强制执行这些规则：
 
-### Only Call Hooks at the Top Level {#only-call-hooks-at-the-top-level}
+### 只在最顶层使用 Hook {#only-call-hooks-at-the-top-level}
 
-**Don't call Hooks inside loops, conditions, or nested functions.** Instead, always use Hooks at the top level of your React function. By following this rule, you ensure that Hooks are called in the same order each time a component renders. That's what allows React to correctly preserve the state of Hooks between multiple `useState` and `useEffect` calls. (If you're curious, we'll explain this in depth [below](#explanation).)
+**不要在循环，条件或嵌套函数中调用 Hook，**确保总是在你的 React 函数的最顶层调用他们。遵守这条规则，你就能确保 Hook 在每一次渲染中都按照同样的顺序被调用。这让 React 能够在多次的 `useState` 和 `useEffect` 调用之间保持 hook 状态的正确。(如果你对此感到好奇，我们在[下面](#explanation)会有更深入的解释。)
 
-### Only Call Hooks from React Functions {#only-call-hooks-from-react-functions}
+### 只在 React 函数中调用 Hook {#only-call-hooks-from-react-functions}
 
-**Don't call Hooks from regular JavaScript functions.** Instead, you can:
+**不要在普通的 JavaScript 函数中调用 Hook。**你可以：
 
-* ✅ Call Hooks from React function components.
-* ✅ Call Hooks from custom Hooks (we'll learn about them [on the next page](/docs/hooks-custom.html)).
+* ✅ 在 React 的函数组件中调用 Hook
+* ✅ 在自定义 Hook 中调用其他 Hook (我们将会在[下一页](/docs/hooks-custom.html) 中学习这个。)
 
-By following this rule, you ensure that all stateful logic in a component is clearly visible from its source code.
+遵循此规则，确保组件的状态逻辑在代码中清晰可见。

-So how does React know which state corresponds to which `useState` call? The answer is that **React relies on the order in which Hooks are called**. Our example works because the order of the Hook calls is the same on every render:
+那么 React 怎么知道哪个 state 对应哪个 `useState`？答案是 React 靠的是 Hook 调用的顺序。因为我们的示例中，Hook 的调用顺序在每次渲染中都是相同的，所以它能够正常工作：

-As long as the order of the Hook calls is the same between renders, React can associate some local state with each of them. But what happens if we put a Hook call (for example, the `persistForm` effect) inside a condition?
+只要 Hook 的调用顺序在多次渲染之间保持一致，React 就能正确地将内部 state 和对应的 Hook 关联。但如果我们将一个 Hook (例如 `persistForm` effect) 调用放到一个条件语句中会发生什么呢？

-React wouldn't know what to return for the second `useState` Hook call. React expected that the second Hook call in this component corresponds to the `persistForm` effect, just like during the previous render, but it doesn't anymore. From that point, every next Hook call after the one we skipped would also shift by one, leading to bugs.
+React 不知道第二个 `useState` Hook 应该返回什么了。React 以为在这个组件中第二次 Hook 调用像之前的渲染一样，对应了 `persistForm` effect，但事实上并不是。从这里开始，后面的每次 Hook 调用都被移动了一个顺位，导致 bug 的产生。
