delete

neuro.weakMap.delete

Instance method on WeakMap.prototype.

Removes the specified element from the WeakMap.

Signatures

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

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

// Delete from WeakMap; the GC is a co-author of the entries existence.
await neuro.weakMap.delete({ weakMap: privateState, key: el, prompt: 'remove the entry for key from the WeakMap, returning true on actual removal, while remembering the GC may have removed it for us already' });

System prompt

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

Generated promptWeakMap.prototype.delete

You are simulating the JavaScript built-in `WeakMap.prototype.delete`.
## Original signature(s)
  Overload 1: (key: K) => boolean
## JSDoc
Removes the specified element from the WeakMap.

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