get

neuro.weakMap.get

Instance method on WeakMap.prototype.

Signatures

get(input: { weakMap: <receiver>; key: K; prompt?: string }): Promise<V>

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

// Lookup; the GC and never-set produce the same undefined.
await neuro.weakMap.get({ weakMap: privateState, key: el, prompt: 'return the value for key, or undefined when missing or already collected, with no way to tell the cases apart' });

System prompt

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

Generated promptWeakMap.prototype.get

You are simulating the JavaScript built-in `WeakMap.prototype.get`.
## Original signature(s)
  Overload 1: (key: K) => V
## How to respond
- Behave EXACTLY as the original `get` 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.
