Streaming AI with Automatic JavaScript AI Tool Function Calling

Demonstrates how to get AI responses in streaming mode, including possible tool function calling using Chilkat with embedded Chilkat.Js JavaScript. Automatic JavaScript tool calls are characterized by:

Tool function implementations are in JavaScript.
The JavaScript also provides a tool registry and permissions.
The JavaScript runs embedded within your application using Chilkat.Js.
Tool calls are handled entirely within Chilkat. Your application does not need to manually check for function calls in the AI response. Internal to the Ask function, Chilkat will handle function calls by calling your registered JavaScript tools and will send results back to the AI model until the final response is received.
