Async

Errors are values: SafePromise turns a promise that may reject into one that resolves to a result, and WithCleanup runs a cleanup either way.

import { SafePromise } from "@pdfking/tfunc"

const result = await SafePromise(Promise.reject(new Error("Failed")))
result.error?.enum // "INTERNAL_ERROR"

• Wait: WaitPromises for an array or a record of promises, Sleep
• Stream: MapAsync, FilterAsync, Collect
• Share: Channel, Broadcast, LockManager

For plain iterables, see Sequences.
