Asynchronous Definition:

In general, asynchronous refers to things that do not happen simultaneously or concurrently in time.

                function function1(){
                    setTimeout(() => {console.log('Task 1');}, 3000);
                };
            
            
                function function2(){
                    console.log('task 2');
                    console.log('task 3');
                    console.log('task 4');
                }
            
            
                function1();
                function2();

Run Code

Let’s break it down:

function1:

This function simulates an asynchronous operation (such as fetching data from an API) using setTimeout. It waits for 3000 milliseconds (3 seconds) and then logs “Task 1”.

function2 Will run without waiting for function one to finish. It is independent

.

function2:

This function logs “task 2”, “task 3”, and “task 4” synchronously (immediately).

The order of execution is as follows:

“task 2”

“task 3”

“task 4”

“Task 1” (after 3 seconds)
