react18以前 react有Transaction机制,可以给react的事件的开头和结尾附上isBathingUpdate变量的赋值,开头为true,结束为false。 简单来说,在 Transaction 的 initialize 阶段,一个 update queue 被创建。在 Transaction 中调用 setState 方法时,状态并不会立即应用,而是被推入到 update queue 中。函数执行结束进入 Transaction 的 close 阶段,update queue 会被 flush,这时新的状态会被应用到组件上并开始后续 Virtual DOM 更新等工作。 react18之后 https://zhuanlan.zhihu.com/p/382216973
