试试这样

```js
import React, { useState, useEffect } from "react";

export default function Counter() {
const [count, setCount] = useState(10);

useEffect(() => {
const id = setInterval(() => {
setCount((c) => c - 1);
}, 1000);
if (count === 0) {
clearInterval(id);
console.log("执行到了这里");
}

return () => clearInterval(id);
}, [count]);

return <h1>{count}</h1>;
}
```
