Argues that ES2017 async/await is a native replacement for generator-based co‑routines and library patterns (co Bluebird redux‑saga), demonstrates sequential code versus parallel with Promise.all and aggregates like Promise.race / any / some, shows that async functions always return a Promise, exposes a practical pitfall where forEach can't await (nested callbacks don’t pause, need serial reduce), presents async iteration and for await...of (stage‑3) and notes the controversial usefulness and danger of top‑level await food gun.
