How does the React Context API work under the hood?

Question

So far I can only find descriptions of how to use the Context API, but not how it works, especially how consumer components are triggered to re-render. Links to source code would be awesome!

Have at it – Dah

@PatrickRoberts this seems to just show the objects that are defined that are used by the runtime (e.g. $$typeof: REACT_CONTEXT_TYPE,) to do stuff, but I don't really know much about how the runtime works. I was looking more for links to Fiber code + a brief explanation to help get me started digging – Drive
