Start by checking your connections. If you have the AirPods or AirPods Pro, make sure the case is fully plugged in or properly set on the wireless charger (use Apple cables or Magsafe chargers if possible). Allow your AirPods to charge for at least 15 minutes. If you have the AirPods Max, allow them to charge for at least five minutes. Then, open the case and hold them near your iPhone or iPad. You should then see the charging icon appear when looking at the battery status. If that doesn't work, contact Apple Support.。业内人士推荐PDF资料作为进阶阅读
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.
