Asynchronous loops are necessary when there is a large number of iterations involved or when the operations within the loop are complex. But for simple tasks like iterating through a small array, there is no reason to overcomplicate things by using a complex recursive function.

What is the purpose of async in this code?

The async keyword enables the await keyword, which lets the compiler know that we’ll need the return value of the function, but not right away. As a result, we don’t need to block the call and can continue running other tasks until the awaited value is needed.

So when NOT to use async?

1. A micro-service has very small CPU-bound operations and is always bombarded with requests.
2. A service is calling a database that cannot scale.
3. If an application which has very slow I/O bound work but does not receive a lot of requests and thus does not need to scale.
