href="https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty" target="_blank" rel="noreferrer"><code>Object.defineProperty</code></a> 把这些 property 全部转为 <a href="https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Guide/Working_with_Objects#%E5%AE%9A%E4%B9%89_getters_%E4%B8%8E_setters" target="_blank" rel="noreferrer">getter/setter</a>。</p><p>每个组件实例都对应一个 <strong>watcher</strong> 实例，它会在组件渲染的过程中把“接触”过的数据 property 记录为依赖。之后当依赖项的 setter 触发时，会通知 watcher，从而使它关联的组件重新渲染。</p></blockquote><p>Vue2的响应式原理，利用的是 <code>Object.defineProperty()</code> 的 <code>setter</code> 属性：</p><p><code>defineProperty()</code> 方法用于<strong>精确</strong>定义一个对象的属性，能够指定属性的各种特征，其中的 <code>set</code> 属性能够为对象指定一个 <code>setter</code> 函数，每次该属性的值发生修改，就会调用此函数。</p><blockquote><p>更多可以配置的属性请参看：<a href="https://juejin.cn/post/7088335075061792782" target="_blank"
