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.
当然它也有优点：长得挺可爱、很小，揣出去还能当个社交谈资。让我最喜欢的一点是，它有两个耳机孔！ 一个平衡口，一个 3.5mm 接口，甚至能一起工作！这让我想起了上学时和好同学分享同一副耳机的青春岁月。现在有了这玩意儿，你可以和另外三个好朋友一起分享音乐了，四人同乐就非常的生草。，这一点在新收录的资料中也有详细论述
