Structured Concurrency vs. JavaScript’s Async Primitives
Structured Concurrency: Fixing JavaScript’s Async Chaos (Why Promises Leak & How to Stop It)
Structured concurrency is the programming paradigm you need to understand if you care about scalable, reliable code. In this video, we break down:
🔹 What structured concurrency is (and why it’s the “structured programming” revolution of our time).
🔹 The fatal flaws of JavaScript Promises: Why Promise.race and Promise.all silently leak memory (and how this explodes in production).
🔹 Lexical scoping for async: How binding tasks to code blocks prevents leaks, just like variables in functions.
🔹 Why async/await fails: What happens when a Promise never resolves? Spoiler: Your entire call stack becomes a zombie.
🔹 The Affection framework solution: How structured concurrency lets outer scopes control async lifetimes, ensuring no resource is left dangling.
