The modern, Promise-based JavaScript interface for asynchronous network requests, replacing `XMLHttpRequest` with a cleaner, more flexible pipeline.

Fetch API provides the global `fetch()` method for resource retrieval: it returns a Promise resolving to a `Response` object. This is a significant upgrade from the older `XMLHttpRequest` model, offering native Promise integration for cleaner async/await syntax. It operates on core concepts: the `Request` and `Response` interfaces, plus the `Headers` object for control over HTTP headers. Use `fetch(url, options)` to handle requests, then chain `.json()` or `.text()` on the Response to extract data, ensuring you check `response.ok` for non-network HTTP error status codes (e.g., 404 or 500).

## Recent Public Talks and Demos

### [Managing UI for Generative AI in JavaScript](https://amsterdam.aitinkerers.org/talks/rsvp_9j1JRHylu3A)

LLMs don’t return data the way REST APIs do — they stream, retry, vary by context, and operate in pipelines. This talk shows how to rethink UI state management for generative flows using modern JavaScript. We'll live-demo a small agentic RAG overlay on top of any site, with real-time updates, streaming output, and context-aware retries. We'll also show how to model each stage (retrieval, generation) as state machines using union types — and why that matters for user trust and product UX.
