Promise vs Async await.
This is most debated and is a whole topic in itself. The major difference in Promise is the use of .then which is nested and it eventually makes too make nested functions and reduces the maintainability and readability of the code.
On the other hand async await makes the code look more synchronous and readable.
At the end both aid to achieve the same task.
