Understanding async and await
The async and await syntax manages the same concepts covered in the previous section; however, there are some nuances. Instead of simply spawning off threads, we create futures and then manipulate them as and when needed.
In computer science, a future is an unprocessed computation. This is where the result is not yet available, but when we call or wait, the future will be populated with the result of the computation. Another way of describing this is that a future is a way of expressing a value that is not yet ready. As a result, a future is not exactly a thread. In fact, threads can use futures to maximize their potential. For instance, let us say that we have several network connections. We could have an individual thread for each network connection. This is better than sequentially processing all connections, as a slow network connection would prevent other faster connections from being processed down the line until it itself is processed, resulting...
