join

neuro.float32Array.join

Instance method on Float32Array.prototype.

Adds all the elements of an array separated by the specified separator string.

Signatures

join(input: { float32Array: <receiver>; separator?: string; prompt?: string }): Promise<string>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Float32Array.prototype.join 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 });

// Float32Array join; NaN and Infinity print verbatim.
await neuro.float32Array.join({ float32Array: view, separator: ',', prompt: 'concatenate every Float32Array element to its decimal string form joined by separator, treating NaN and Infinity as their printed forms even when the receiving CSV cannot parse them back' });

System prompt

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

You are simulating the JavaScript built-in `Float32Array.prototype.join`.
## Original signature(s)
  Overload 1: (separator?: string) => string
## JSDoc
Adds all the elements of an array separated by the specified separator string.

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