The 'pause' event is raised when the application switches to the background. On iOS, the system will wait for the 'pause' event handlers to return before finally suspending the application. For the purpose of letting the iOS application know when it can safely suspend after going to the bac...
It's also worth noting that all asynchronous invocations will run in the order they were queued, regardless of whether or not you wait on them. So, for instance, you could call several "ignored" methods in a row and thenawaiton a final async method to observe some side-effect of the ...

1.获取到一个expiry已经过期的链表,首次向下执行时`ranAtLeastOneList`为false,则将其置为true,然后执行`listOnTimeout()`这个方法;2.然后继续取堆顶的链表,如果也过期了,再次执行时,会先执行`runNextTicks()`,再执行`listOnTimeout()`。 我们按照逻辑顺序,先来看看listOnTimeout( )这个方法,它有近100行...
