JavaScript Operations
Comprehensive reference for modern JavaScript and Node.js — async patterns, module systems, runtime internals, and ES2022-2025 features.
Async Decision Tree
What are you doing asynchronously?
│
├─ Simple one-off operation (DB query, HTTP call)
│ └─ async/await with try/catch ✓ default choice
│
├─ Multiple independent operations
│ ├─ All must succeed → Promise.all([a(), b(), c()])
│ ├─ Don't care about failures → Promise.allSettled([...])
│ └─ First one wins → Promise.race([...]) or Promise.any([...])
