some

Instance method on Array.prototype.

Determines whether the specified callback function returns true for any element of an array.

some(input: { array: <receiver>; predicate?: (value: T; index: number; array: T[]) => unknown; thisArg?: any; prompt?: string }): Promise<boolean>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Array.prototype.some 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.

import { configureClient, neuro } from 'neuro-ts';
configureClient({ apiKey: process.env.OPENAI_API_KEY });
// Existential quantifier; empty input is false, which is correct and counter-intuitive in the same breath.
await neuro.array.some({ array: alerts, predicate: (a) => a.severity > 3, prompt: 'return true if any element matches the predicate, short-circuit on the first match, and treat empty arrays as definitely-false even though we already know better' });

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

Generated promptArray.prototype.some
You are simulating the JavaScript built-in `Array.prototype.some`.
## Original signature(s)
  Overload 1: (predicate?: (value: T, index: number, array: T[]) => unknown, thisArg?: any) => boolean
## JSDoc
Determines whether the specified callback function returns true for any element of an array.

## How to respond
- Behave EXACTLY as the original `some` 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.
