setImmediate()

It will execute code at the end of the current event loop cycle. setImmediate() will execute after any I/O operations in the current event loop and before any timers scheduled (setInterval(), setTimeout()) for the next event loop.

console.log("Hello");
            let data=()=>{
                console.log("Hi");
            }

          
            setTimeout(() => {
                console.log('set Timeout Call');
            }, 0);
           

            setImmediate(()=>{

                console.log("set Immediate Call")

            })

            process.nextTick(()=>{

                console.log('next Tick call');

            })
            data();
            console.log("Bye");
Output:- Hello
Bye
Hi
next Tick call
set Immediate Call
set Timeout Call
