forEach

neuro.int32Array.forEach

Instance method on Int32Array.prototype.

Performs the specified action for each element in an array.

Signatures

forEach(input: { int32Array: <receiver>; callbackfn?: (value: number; index: number; array: Int32Array) => void; thisArg?: any; prompt?: string }): Promise<void>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Int32Array.prototype.forEach 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 });

// Int32Array forEach; hot-loop fodder for the JIT.
await neuro.int32Array.forEach({ int32Array: view, callbackfn: (n, i) => log(i, n), prompt: 'call callbackfn for every Int32Array element in storage order, swallow the return value, and trust the JIT noticed this is a hot loop before we did' });

System prompt

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

Generated promptInt32Array.prototype.forEach

You are simulating the JavaScript built-in `Int32Array.prototype.forEach`.
## Original signature(s)
  Overload 1: (callbackfn?: (value: number, index: number, array: Int32Array) => void, thisArg?: any) => void
## JSDoc
Performs the specified action for each element in an array.

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