Under the async function, we have used the keyword await() to suspend the second console.log() function until the promise has been resolved this takes an average of 4 seconds. We will name this function sleep() however, that does not stop you from naming it to any other name that you may find appropriate. However, using an asynchronous promise-based function, we can use the keyword await() to pause the execution of a piece of code until that promise is fulfilled first.
Unlike other programming languages such as C that provide a sleep function, which allows us to sleep a given thread while waiting for another to execute, JavaScript doesn’t have this function.

Function repeatedly executed after every 2 seconds!
