Interview question -- event cycle

First execute the first round of macro tasks （ Script ） The code in ： Sync ==> Micro task ==> Code in the next round of macro tasks
In macro task ： Sync ==> Micro task ==> Macro tasks in the next queue

In the next round of queued macro tasks ： Perform synchronization ==> Perform micro tasks ==. Continue to queue when encountering macro tasks ==> Execute the next queued macro task

In the next round of queued macro tasks ： Perform synchronization ==> Perform micro tasks ==. Continue to queue when encountering macro tasks ==> Execute the next queued macro task

In the next round of queued macro tasks ： Perform synchronization ==> Perform micro tasks ==. Continue to queue when encountering macro tasks ==> Execute the next queued macro task

So it circulates ==> It's the cycle of events .
summary ：1. The macro task runs first Micro task post run
2.then It's a micro task Global scripts and calculators are red tasks
