event loop

logworld() from web api -> to task queue

logworld() from task queue -> to call stack

empty call stack means the event loop done!

but if setTimeout time is 0 ?

function logWorld() {
    console.log('world');
}

function main() {
    console.log('hello');
    setTimeout(logWorld,0);
    console.log('goodbye');
}

main();

same thing happened
