-There are no tricks here. Just replace `.catch` with `try...catch` inside `demoGithubUser` and add `async/await` where needed:
+没有窍门，只需要在 `demoGithubUser` 中使用 `try...catch` 替换 `.catch` 然后在我们需要的地方添加 `async/await`：

+## Async 函数

-Let's start with the `async` keyword. It can be placed before function, like this:
+我们从`async` 关键字开始。它可以放在函数前，就像这样：


async 与前面的从之间缺少空格

-...We could explicitly return a promise, that would be the same:
+...我们可以明确返回 promise，内容相似:


省略号没有使用中文的省略号

固定格式不用换

 */!*

-  alert(result); // "done!"
+  alert(result); // “完成！”


语句后面的 "done!" 应保持不变，程序返回值就是 "done!"

-````smart header="`await` won't work in the top-level code"
-People who are just starting to use `await` tend to forget that, but we can't write `await` in the top-level code. That wouldn't work:
+````smart header="`await` 在高级代码中无效"


『高级代码』=> 『顶层代码』

+## 总结

-The `async` keyword before a function has two effects:
+函数前的 `async` 关键字有两个副作用：


副作用 => 作用

-1. If it's an error, the exception is generated, same as if `throw error` were called at that very place.
-2. Otherwise, it returns the result, so we can assign it to a value.
+1. 如果有 error，就会产生异常，就像在那个地方调用了 `throw error` 一样。


error => 错误

-Together they provide a great framework to write asynchronous code that is easy both to read and write.
+它们一起为编写易于阅读的异步代码提供了一个很好的框架。

+它们一起为编写易于阅读的异步代码提供了一个很好的框架。

-With `async/await` we rarely need to write `promise.then/catch`, but we still shouldn't forget that they are based on promises, because sometimes (e.g. in the outermost scope) we have to use these methods. Also `Promise.all` is a nice thing to wait for many tasks simultaneously.
+对于 `async/await`，我们很少需要编写 `promise.then/catch`，按我们不应该忘记它们是基于 promise 的。因为有时（例如，在最外面的范围）我们必须使用这些方法。同样，对于同时等待许多人物，`Promise.all` 是一中好方法。


按我们不应该忘记它们是基于 promise 的。=> 但我们不应该忘记它们是基于 promise 的，

因为有时（例如，在最外面的范围）我们必须使用这些方法 => 因为有时（例如，在最外面的范围）我们不得不使用这些方法

同样，对于同时等待许多人物，Promise.all 是一中好方法 => Promise.all 也是一个很好的东西，它能够同时等待很多任务。
