Fetch API
The default web interface for making requests and reading responses
Core Idea
The Fetch API is the standard web interface for sending requests and handling responses. Because fetch() returns a Promise instead of an immediate value, it naturally introduces waiting, failure handling, and async control flow.
Why It Matters Here
Mathbong uses the Fetch API across SvelteKit loading, FastAPI examples, and browser-side exercises. It is the first practical bridge that turns a UI into a real client of a server.
