| Because the operating system is not involved, *context switching* in the async world is very fast. Furthermore, async tasks have much lower memory overhead than operating system threads. This makes async programming a good fit for systems which need to handle very many concurrent tasks and where those tasks spend a lot of time waiting (for example, for client responses or for IO). | ||

| Async programming also offers the programmer fine-grained control over how tasks are executed (levels of parallelism and concurrency, control flow, scheduling, and so forth). This means that async programming can be expressive as well as ergonomic for many uses. |
