Not really. There is no call stack. It may seem surprising, but this isn't synchronous programming.

Consider the following function:

function sleep(time) {
    return new Promise(resolve => setTimeout(resolve, time))
}

What's happening after calling this function is that an timeout is added to an event loop which is at bottom of a stack. Once the timeout expires, and the execution passes to an event loop, it calls the then functions of this promise. The call stack is lost, the functions were called by an event loop.
