Talk: The ReactJS Landscape
Luke Vanderhart's talk at Clojure/West is about the ReactJS Landscape.
Background
ReactJS appeared from Facebook last year in silence and without fanfare (from my view anyways!) but recent months has had an explosion on the web frameworks space, in particular in Clojure because of the common thread of immutablility running through the core concepts.
Since Facebook announced it in June, we have seen several incarnations of React in Clojure: Om, Quiescent, and Reagent.
Why it matters
ReactJS is the View in MVC apps and is a declarative library for describing a user interface, it can figure out what parts of the application to redraw on an update. With the popularity of single page applciations this is key to making a fast and responsive user interface.
