You might be able to foster a deeper appreciation for some of these ideas by playing with Elm a little bit. Some time ago, they implemented time-travel in the standard debugger, and its a really wonderful feature. The site also has some demo apps that make it easy to play around with that time travel support. I agree that, currently, languages and frameworks don’t make things like time travel easy, insofar as such a feature is not often built in. However, technologies like Flux and Vuex are paving the way for such things to become mainstream. It’s worth pointing out, too, that both were inspired by Elm’s runtime architecture. Functional programming is, only in the last half-decade or so started to see a relatively dramatic rise in popularity. I think this trend will continue for a long time to come. For that reason, it’s worth learning more about these concepts.
