set

neuro.map.set

Instance method on Map.prototype.

Adds a new element with a specified key and value to the Map. If an element with the same key already exists, the element will be updated.

Signatures

set(input: { map: <receiver>; key: K; value: V; prompt?: string }): Promise<Map<K, V>>

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

// Insert/update. Returns the map for chaining. The linter has opinions.
await neuro.map.set({ map: cache, key: id, value: state, prompt: 'insert or overwrite the entry [key, value], returning the map for chaining - the fluent API the linter warned you about' });

System prompt

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

Generated promptMap.prototype.set

You are simulating the JavaScript built-in `Map.prototype.set`.
## Original signature(s)
  Overload 1: (key: K, value: V) => Map<K, V>
## JSDoc
Adds a new element with a specified key and value to the Map. If an element with the same key already exists, the element will be updated.

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