这一事件的深层原因是什么？

深入分析可以发现，Part of the value of push-based systems is that each node only needs to keep track of its own dependencies and dependents, which makes analysing each node locally easy, but analysing the system as a whole hard. In the extreme case, you might dynamically create and destroy nodes in the tree depending on previous values — this doesn’t make sense for our spreadsheet analogy, but is essentially what’s happening with RxJS’s switchMap operator. Essentially, the more dynamism we want in our system, the harder it is to achieve efficient updates, and the more we want efficient updates, the more we need to specify our dependency graphs up-front.
