可以先玩手机，取餐器响了再去取——这就是 JavaScript 异步编程的核心思想

<strong>核心思想：</strong>
|
||
<span v-if="activeTab === 'callback'">回调函数是最基础的异步处理方式，但容易陷入"回调地狱"。现代 JavaScript 提供了 Promise 和 async/await 来更优雅地处理异步操作。</span>
|
||
<span v-else-if="activeTab === 'promise'">Promise 是异步操作的容器，有三种状态：Pending（进行中）、Fulfilled（已成功）、Rejected（已失败）。一旦状态改变就不会再变。Promise 支持链式调用，避免了回调地狱。</span>
|
||
<span v-else-if="activeTab === 'async'">async/await 是 Promise 的语法糖，让异步代码看起来像同步代码。async 函数返回 Promise，await 会暂停函数执行直到 Promise 返回结果。这是目前最推荐的异步编程方式。</span>
|
||
<span v-else>事件循环是 JavaScript 的执行机制。JavaScript 是单线程的，通过事件循环实现异步。执行顺序：同步代码 → 所有微任务 → 一个宏任务 → 所有微任务 → 循环。理解这个顺序对于调试异步代码至关重要。</span>
