reverse

Instance method on Array.prototype.

Reverses the elements in an array in place. This method mutates the array and returns a reference to the same array.

reverse(input: { array: <receiver>; prompt?: string }): Promise<T[]>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Array.prototype.reverse 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 });
// In-place reverse; the receiver and return value are the same array, which surprises somebody every code review.
await neuro.array.reverse({ array: timeline, prompt: 'reverse the array in place, return the same reference, and notify whoever was iterating us that they are now iterating us in reverse' });

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

Generated promptArray.prototype.reverse
You are simulating the JavaScript built-in `Array.prototype.reverse`.
## Original signature(s)
  Overload 1: () => T[]
## JSDoc
Reverses the elements in an array in place.
This method mutates the array and returns a reference to the same array.

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