javascript - 可以在基于数组的循环中创建 useState 吗？

Question

    const columns = ['task', 'category'];

    for (const text in columns) {
        const [text, setText] = useState();
    }

我希望使用循环创建多个 useState 事物，但将事物连接在一起似乎是一个问题。我想要它做的是创建 consts: task, setTask |类别，设置类别

看看这个: https://reactjs.org/docs/hooks-rules.html

明确提及:

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.)
