I'm interested to how this applies to Reactive application-UI programming (e.g. React+Flux).<p>React has a powerful unidirectional data->UI flow model, but I haven't seen an expressive language for the other awy (putback functions), besides UPDATE statements in various db query language, but I figure there's gotta be more symmetry between the languages expressing data->UI and UI->data.<p>Is there a video of this talk?
