5 architectures of asynchronous JavaScript
summary
Covers the actual mechanics behind asynchronous JavaScript and compares 5 approaches: callbacks, events, promises, coroutines, reactive streams with concrete code patterns and gotchas. Explains event loop and run to completion rule, shows Promise.all, Promise.race and Promise.any behavior, demonstrates chaining vs parallel execution, implements generators + promises as coroutines (async/await equivalent), sketches CSP channels for coroutine communication and contrasts RxJS streams. Good if you want hands‑on examples of when each technique fails or scales.
