 > Flux reference: Vuex getters can be roughly compared to [`mapStateToProps`](https://github.com/rackt/react-redux/blob/master/docs/api.md#connectmapstatetoprops-mapdispatchtoprops-mergeprops-options) in Redux. However, because they leverage Vue's computed properties memoization under the hood, they are more efficient than `mapStateToProps`, and more similar to [reselect](https://github.com/reactjs/reselect).
