 # Why async-await?
 Asynchronous programming has long been a useful way to perform operations that don’t necessarily need to hold up the flow or responsiveness of an application. Generally, these are either compute-bound operations or I/O bound operations. Compute-bound operations are those where computations can be done on a separate thread, leaving the main thread to continue its own processing, while I/O bound operations involve work that takes place externally and may not need to block a thread while such work takes place. Common examples of I/O bound operations are file and network operations.
