Various JavaScript toolkits have been offered the past few years to enable the use of functional patterns on the frontend. While these tools promote composable APIs and pure functions to a certain degree, UI programming is still encumbered with stateful MV*-like frameworks, or just plain dirty DOM manipulation. Facebook's React is an interesting approach to UI programming in the browser that does away with manual DOM manipulation all together, and more closely resembles classic UI programming. Combine this approach with the immutable data structures of Clojurescript, and we're really getting somewhere. In this talk I will explore the path to fully functional UI programming in the browser through React, Clojurescript, Om (React for Clojurescript) and other tools.
