A Design Space Exploration of Async/Await

A Design Space Exploration of Async/Await

The article examines async/await, a language feature that simplifies asynchronous programming. It reviews how async/await compares to callbacks and promises, discusses trade‑offs such as error handling, cancellation, and performance overhead, and considers language‑level support. The author also explores potential future improvements and design alternatives that could further enhance developer experience and runtime efficiency in modern runtimes.
