我们分析diff算法是从reconcileChildren开始的,之前从setState -> enqueueSetState(UpdateQueue) -> scheduleUpdate -> performWork -> workLoop -> beginWork -> finishClassComponent -> reconcileChildren相关的部分就不过多介绍了,需要注意的是beginWork会将一个一个的Fiber来进行diff,期间是可中断的,因为每次执行下...

只是再次在该层中循环系统寻找一个能够多路复用的连接点,最高层的while及其底端的child = child.sibling;是为了更好地再次从子连接点中寻找一个key与tag同样的可多路复用连接点,此外删掉连接点不容易确实从链表里边把连接点删掉,仅仅打一个delete的tag,当commit的情况下才会真真正正的去删掉。

Broadly, jsdiff's diff functions all take an old text and a new text and perform three steps: Split both texts into arrays of "tokens". What constitutes a token varies; indiffChars, each character is a token, while indiffLines, each line is a token. ...
