Structured Concurrency in JavaScript: Beyond Promise.all

The Problem with Unstructured Async Code JavaScript async code has a scope problem. You fire off promises and hope they complete—or fail—cleanly. When something goes wrong mid-flight, cleanup is your responsibility. // Classic problem: partial failure async function loadDashboard(userId: string) { const [user, orders, analytics] = await Promise.all([ getUser(userId), getOrders(userId), // This throws after 2 seconds getAnalytics(userId), // This is still running!
