	```js
	try {
	const controller = new AbortController();
	const timeoutId = setTimeout(() => controller.abort(), 5000);
	const res = await fetch(url, { signal: controller.signal });
	const body = await res.json();
	} catch (e) {
	if (e.name === "AbortError") {
	// Notify the user of abort.
	// Note this will never be a timeout error!
	} else {
	// A network error, or some other problem.
	console.log(`Type: ${e.name}, Message: ${e.message}`);
	}
	} finally {
	clearTimeout(timeoutId);
	}
	```

finally 中无法读取到 try 代码块中的 timeoutId 变量

你期望看到什么？

let timeoutId;
try {
  const controller = new AbortController();
  timeoutId = setTimeout(() => controller.abort(), 5000);
  const res = await fetch(url, { signal: controller.signal });
  const body = await res.json();
} catch (e) {
  if (e.name === "AbortError") {
    // Notify the user of abort.
    // Note this will never be a timeout error!
  } else {
    // A network error, or some other problem.
    console.log(`Type: ${e.name}, Message: ${e.message}`);
  }
} finally {
  clearTimeout(timeoutId);
}
