我试图部署到 Vercel 我之前已经在其他项目中完成了它，但在这种情况下，构建失败，它提到它没有找到页脚组件，构建在本地机器上完美运行。

我目前正在学习如何使用ES8的fetch,async等待我目前有这个代码可以工作:

const url = "https://api.icndb.com/jokes/random";

async function tellJoke() {
  let data = await (await fetch(url)).json();
  return data.value.joke;
}

tellJoke().then(data => console.log(data));

安慰:

"Chuck Norris can dereference NULL."

但是我发现了一个使用箭头功能的片段,问题是我不知道如何在我当前的例子中按照我的方式返回我的值.

片段:

const fetchAsync = async () => 
await (await fetch(url)).json()

如果这不是最佳做法让我知道,欢迎任何进一步阅读.
