JavaScript has async/await, but it still lacks structured concurrency. That gap shows up as ad-hoc cancellation, fragile cleanup, and async code that no longer behaves like synchronous code once things get even slightly complex. This post argues that the missing piece isn’t a heavier abstraction, but a small runtime polyfill for structured concurrency: scoped lifetimes, parent/child tasks, and guaranteed cleanup. Is JavaScript ready for structured concurrency? |
