优化阶段
如果type值为2,那么该节点是不包含变量的纯文本节点,它就肯定是静态节点,返回true;
应改为:

https://nlrx-wjc.github.io/Learn-Vue-Source-Code/start/#_1-%E5%89%8D%E8%A8%80 说的是2.6.11版本 但是我看贴图上的nextTick的源码 不是2.6.11的源码 大佬~ 我特意去找了一下vue2库中的分支代码 https://github.com/vuejs/vue/blob/v2.6.11/src/core/util/next-tick.js 确实不一样, 没有 MessageChannel 与之对应的应该是 MutationObserver
最后一句,~~看看Vue中的虚拟DOM时怎样的。~~应改为 是怎样的

问题:计算属性不会通知视图更新,而是计算属性依赖的属性通知
计算属性的用到的属性变化时:
1、会通知计算属性的watcher把dirty设置为true,等待下一次取值
2、会通知使用这个计算属性的组件实例的watcher更新视图
如题
不太理解提到的静态节点和文本节点的区别在哪里,前面说只有六种节点,为什么现在出现了第七种节点呢?
