Console 输入任何内容直接报错 EvalError: Possible side-effect in debug-evaluate 看起来是 Chrome 的 bug, 可以使用以下方式临时解决这个问题
/reactor/core/publisher/Flux.java doOnSubscribe /** * Add behavior (side-effect) triggered when (this, onSubscribe, null, null, null, null, null, null); } doOnRequest /** * Add behavior (side-effect doOnSignal(this, null, null, null, null, null, consumer, null); } doOnNext /** * Add behavior (side-effect doOnSignal(this, null, onNext, null, null, null, null, null); } doOnError /** * Add behavior (side-effect All these events are represented as a {@link Signal} * that is passed to the side-effect callback
that a Callable may have side-effects (e.g. writing to a file), while a Supplier should generally be side-effect
The completion order of the children affects the // side-effect order. We don't want to // schedule our own side-effect on our own list because if end up // // If we have an alternate, that means this is an update and we need // to schedule a side-effect
captureCommitPhaseError(effect, error); } } effect = effect.nextEffect; } } 解析: 循环执行 effect 链上的副作用(side-effect mountTag: number, finishedWork: Fiber, ) { //FunctionComponent 的更新队列 //补充:FunctionComponent的 side-effect updateQueue.lastEffect : null; //如果有副作用 side-effect的话,循环effect 链,根据 effectTag,执行每个 effect if (lastEffect 注意下lastEffect是怎么取到的: root.current.firstEffect.updateQueue.lastEffect 当前 fiber 节点上的 effect 链上第一个有 side-effect
有个什么用呢 function pure(a) { let b = 1 return a + b } 复制代码 纯函数的好处 更有利于单元测试 无副作用(side-effect),不会修改作用域外的值
mountTag: number, finishedWork: Fiber, ) { //FunctionComponent 的更新队列 //补充:FunctionComponent的 side-effect updateQueue.lastEffect : null; //如果有副作用 side-effect的话,循环effect 链,根据 effectTag,执行每个 effect if (lastEffect

As a side-effect, this means that even if the memory is private, several processes might share the
Also, as a side-effect of its monstrous fame, there is an unfathomable degree of help accessible through
reconcileChildFibers // This API will tag the children with the side-effect of the reconciliation / They will be added to the side-effect list as we pass through the // children and the parent.
但是,不管他们是如何的相似,他们还是有一个重大的区别:更改远端跟踪分支只能用git fetch,或者是git push后作为副产品(side-effect)来改变。
【写在前面的话】 ---- 作为嵌入式软件工程师,你是否听说过“无副作用(no side-effect)的代码”这个概念? 如果没有的话,今天的文章你就真的要好好看一看了。 【写在后面的话】 ---- 正如我在此前很多文章中所提到的那样,程序员与编译器之间存在着巨大的信息鸿沟——很多我们甚至都意识不到需要特别强调的重要信息,在编译器看来是并不存在的——“无副作用(no side-effect
Memory map areas are used as a side-effect of calling malloc, directly by mmap and mprotect, and also
reconcileChildFibers 五、reconcileChildFibers 作用: 针对不同类型的节点,进行不同的节点操作 源码: // This API will tag the children with the side-effect They will be added to the side-effect list as we pass through the // children and the parent.
递归控制 严格定义递归函数的作用,包括函数、返回值,side-effect 先一般,后特殊 每次调用必须缩小问题规模 每次问题规模缩小程度必须为1 eg:创建链表 public Node createLinkedList
在内存分配上有边界效应(side-effect)的表达式是允许的,但对其他内存对象产生边界效应的表达式则不行。
