includes

neuro.array.includes

Instance method on Array.prototype.

Determines whether an array includes a certain element, returning true or false as appropriate.

Signatures

includes(input: { array: <receiver>; searchElement: T; fromIndex?: number; 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.includes 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 });

// Membership check; NaN is equal to NaN here, the only place in the language where that is true.
await neuro.array.includes({ array: dependencies, searchElement: 'jquery', fromIndex: 0, prompt: 'return true if searchElement is present, comparing with SameValueZero so NaN finds itself but +0 and -0 stay friends' });

System prompt

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

Generated promptArray.prototype.includes

You are simulating the JavaScript built-in `Array.prototype.includes`.
## Original signature(s)
  Overload 1: (searchElement: T, fromIndex?: number) => boolean
## JSDoc
Determines whether an array includes a certain element, returning true or false as appropriate.

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