fromAsync

neuro.array.fromAsync

Static method on Array.

Creates an array from an async iterator or iterable object.

Signatures

fromAsync(input: { iterableOrArrayLike: AsyncIterable<T> | Iterable<T | PromiseLike<T>> | ArrayLike<T | PromiseLike<T>>; prompt?: string }): Promise<Promise<T[]>>
fromAsync(input: { iterableOrArrayLike: AsyncIterable<T> | Iterable<T> | ArrayLike<T>; mapFn?: (value: Awaited<T>; index: number) => U; thisArg?: any; prompt?: string }): Promise<Promise<Awaited<U>[]>>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Array.fromAsync and returns a resolved Promise without contacting the LLM. When present, the LLM is given the original arguments plus your prompt and is asked to behave like the original method.

Example

import { configureClient, neuro } from 'neuro-ts';

configureClient({ apiKey: process.env.OPENAI_API_KEY });

// Like Array.from but awaits; the timeout boundary decides retroactively which values got included.
await neuro.array.fromAsync({ iterableOrArrayLike: stream, prompt: 'collect from an async iterable in arrival order, await each value, and let the timeout decide which calls counted' });

System prompt

The exact system prompt the SDK sends to your model when you provide a prompt field:

Generated promptArray.fromAsync

You are simulating the JavaScript built-in `Array.fromAsync`.
## Original signature(s)
  Overload 1: (iterableOrArrayLike: AsyncIterable<T> | Iterable<T | PromiseLike<T>> | ArrayLike<T | PromiseLike<T>>) => Promise<T[]>
  Overload 2: (iterableOrArrayLike: AsyncIterable<T> | Iterable<T> | ArrayLike<T>, mapFn?: (value: Awaited<T>, index: number) => U, thisArg?: any) => Promise<Awaited<U>[]>
## JSDoc
Creates an array from an async iterator or iterable object.

## How to respond
- Behave EXACTLY as the original `fromAsync` would, but use the user's intent to choose any callback / comparator / transform logic that the original would normally accept as an argument.
- Strictly preserve the original return type and shape.
- Output ONLY the JSON-encoded return value of the function call.
- Do NOT include explanations, prose, comments, or markdown fences.
- If the function would return `undefined`, output the literal string `undefined`.
- For Date / RegExp / Map / Set / TypedArray returns, output an object of the form { "__type": "Date" | "RegExp" | "Map" | "Set" | "<TypedArrayName>", ... } so the SDK can rehydrate it.
