Something to work with, it did not solve my problem but the understanding is good, thanks.

This is exactly what I need for my project. Javascript is hard when I do it, but simple in your videos.

would it not be nice if to use map method and destructure results with Promise.all...in this case the array can be dynamic and flexible..great explanation and good work:-)

You really explained it perfectly! May I suggest something that is really conflicting in Js asynchronous code...
When you have to perform the same todos, comments & posts inside every iteration of a forEach loop.
How would you suggest to do a Promise.all in that scenario?

I have some doubt I don't know whether this is a silly question to ask.
Somebody, please clear this to me

for example, this is one of the functions in my code

async function ex () {
let i = 1;
while (i >0){
console.log("....No end....");
}
}

Since JS is single-threaded only one task will execute at a time.
How this snippet will execute internally?
I read
All the async tasks are sent to the call back queue.
So is this function also sent to the call back queue? (Since I wrap it in an async), or it won't.

Q2. NodeJS

I have another doubt also
In node js, I read that all heavy jobs are sent to the libuv instead of v8.
so libuv create a separate thread pool for executing those tasks.
In that case, let's say libuv created four threads and let this function execute in one thread. Since it is an infinite loop that one thread will get blocked.
Then the remaining tasks after that function will execute or not?
