I’m not sure how Crank is more “magical” than any other framework. All `this.refresh` does is make the current component execute again. For function components, this means the component gets executed again, and for generator components, this means the generator instance gets stepped through again. I think once you get the hang of generator functions and how yield work it might sort of click what Crank is doing under the hood.

Isn't the point that it's less magical - stuff goes where you expect it and does what you expect, not where the framework magically and by convention places it?
I believe bikeshaving's point above is that you learn the semantics of generator functions in JavaScript and that's your 'magic convention' - one that's not unique to this library because it comes form the languagee
If the OP was saying that Crank is less magical then I agree. Although it always made me sad that we measure APIs based on how little magic they bring. Like go to Disney World or something.
