ASYNC QUEUE – ONE OF MY FAVORITE PROGRAMMING INTERVIEWS (CAN AI BREAK IT?)

Summary from the TLDR Web Dev newsletter

This dev's favorite programming interview question involves an asynchronous queue designed to prevent a faulty server from handling multiple simultaneous requests from a single-threaded client. The interview starts with implementing a `sendOnce` function and then progressively adds complexity with features like minimum delays, `sendMany` functionality, request cancellation, retries, and prioritization. This question tests a candidate's ability to reason about code, handle new requirements, and adapt to a single-threaded environment.
