歡迎來到 React 白話文運動第三篇，今天我們將深入探討 JavaScript 中的非同步操作，並介紹兩個重要的關鍵字：Async 與 Await。在這篇文章中，我們將透過實例演示非同步操作的概念，以及如何使用 Promise、Fetch、Async 和 Await 來更有效地處理非同步程式。
上篇介紹的promise chain的寫法，是已經比原本好維護了沒錯，但是可讀性似乎還是有點不足，其實還可以改成用async/await的寫法，如下:
E
其中，async是非同步的意思，等於是把getData()這個function定義為非同步，因此從console可以看到，test是最先被pri
This insightful article by Vic Lin provides a clear and concise explanation of how async/await can be used to simplify Promise operations in JavaScript. The code examples effectively demonstrate the enhanced readability and maintenance benefits of transitioning from traditional promise chaining to async/await. The comparison before and after the improvement highlights the elegance of the async/await syntax. The article serves as a valuable resource for developers seeking a more streamlined and readable approach to handling asynchronous operations in JavaScript.References for further learning:1.
