async v0.2.0 — write Go concurrency like JavaScript

[burrows99]

async maps the JavaScript concurrency model — Promises, async/await, Promise.all, AbortController — onto idiomatic Go with generics, while goroutines and context.Context run underneath. Zero dependencies.

It's an onboarding ramp for developers coming from JavaScript who think in Promises but are relearning goroutines and channels — built for the 90% "fan out and gather" case, not a replacement for channels.

// JS: const [user, orders] = await Promise.all([getUser(id), getOrders(id)]);
user, orders, err := promise.All2(getUser(id), getOrders(id))

Packages (organized by JS concept):

• promise — New, Await, Then, Finally, All/All2–All8, Race, AllSettled, Any, Retry, Timeout
• abort — Controller, Signal (AbortController / AbortSignal)
• collections — Map, ForEach, Concurrency, Queue (p-map / p-queue)
• timers — SetTimeout, SetInterval, Debounce, Throttle

Panic safety and opt-in cancellation are built in, and errors stay Go-shaped ((T, error), errors.Is/errors.As).

New to Go from JavaScript? The Coming from JavaScript guide shows every pattern side by side with raw Go — and is honest about where the ramp ends.

Feedback very welcome — especially on whether the API feels intuitive coming from JavaScript.
