  • At JSConf 2018 in Iceland the mastermind behind the Redux JavaScript state management library, Dan Abramovich, announced his replacement for Redux called Future-Fetcher.
  • It is widely used with the React.js UI library as well as it’s React Native sister product allowing development of Android and iOS mobile appications.
  • You could also use Redux with Vue.js, but most developers opt for Vuex, the solution from the same team as the UI library.
