i just finished going all of your tutorials, it took some hours throughout some days but I feel more confident with what I didn't know before this. I knew just enough to get up and running and make apps, but this helped me understand what's really going on behind the scenes, thank you!

Thank you sir. Are you planning to make a react native course in the future?

I have a question. This is in regard to another video (JavaScript Synchronous vs. Asynchronous) where you have explained how event loop does the scheduling. In case of Promises, is the code in the 'then' block or after 'await' considered as a callback function? Basically, is it kept in the 'Callback/Task queue' or the 'Job queue'? I think it should be there in the job queue, so that it gets priority over any other callback waiting in the 'Callback/Task queue'. Can you please confirm?

Sir, thanks a lot for the tutorial and the resources. it was really valuable & i really learnt a lot.
I'm unable to find the final video for which you said you'll incorporate all the concepts that you've thought so far. so that it'll be a proper example & illustration.

For example we have a function like this
const getaData=async ()=>{
const data= await userApi();
console.log("hi");
}
Here if userApi takes 1 minute has await will wait until promise return if promise is settled . Then it goes to next line ( here it seems like a blocking a code because console.log("hi") will return after 1 minute which it seems like a blocking code
Sir please can you explain my example if it is wrong
