I have a doubt at 23:31. When the event loop is in 2nd phase and reaches setImmediate, instantly its callback will be pushed to the callback queue. At this loint event loop doesnt know whats ahead of it. It doesnt know process.nextTick is the next line. Why event loop doesnt execute 3rd phase callback even though event loop is in 3rd phase and the stack is empty ?

thanks for the explanation sir but I have a question
setTimeout(() => {
setTimeout(() => {
console.log('nested settimeout finishes');
}, 0);
setImmediate(() => console.log('Immediate 1 finishes'));
}, 0);

why setImmediate() here gets called before the inner setTimeout()
shouldn't the inner setTimeout gets executed before the setImmediate here
because the event loop starts in the timer phase and executes the outer setTimeout then adds the inner setTimeout to the timer phase queue which the event loop is still currently at and then add the setImmediate callback to the third phase

now the event loop is still at the timer phase why the inner setTimeout callback is not executed first before the setImmediate callback that is in the third phase

22:02 that means event loop phases can have nested event loop as well if our program needs if code have call backs in call backs. i think thats the reason call back hell is bad. am i right?

You should be a lecturer by default. I didn't watch it twice before understanding the concept.
