关于无障碍设施为何“建而难用”，不同的路径和策略各有优劣。我们从实际效果、成本、可行性等角度进行了全面比较分析。
维度一：技术层面 — 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.
