如何计算事件循环（NodeJ）的总滴答声？

Question

I'm learning nodejs event loop. I'm curious if we can count total ticks event loop took throughout the application runtime?

setTimeout(() => {
    console.log("Hey there!")
}, 1000);

As per my understanding, event loop will tick total 2 times before the application ends. How can I make node tell me exact number of ticks?

The event loop is a system for scheduling tasks and async operations, it uses Queues and Stack under the hood to process function calls. Whenever you get a result of a function, this means the function was put in the Queue and the pushed in to the stack. This way we have non-blocking operation. What you are trying to do does not make any sense to me, every time you get a log from a function it means this function was processed both by the queue and the stack.
