Why we used async & await?
Async and await are used to make the code easier to write and read. Also, the agenda behind rolling out this feature is to deal with the promises and functions chaining in the Node. Where the functions do not need to be chained just one after another, simply call the await function that returns the promise. On the other hand, the function async should be declared before returning a promise by awaiting a function.
