If a getter returns a function with an argument, that argument will be the argument of the getter:
getters: { ... getWorldWonder: state => nth => state.worldWonders[nth]}
In our recipe, a practical example could specify the average cost of a house in the getter from the previous paragraph:
const store = new Vuex.Store({ state: { bitcoin: 600, rate: 1000 }, getters: { euro: state => state.bitcoin * state.rate, houses: (state, getters) => averageHousePrice => { return getters.euro() / averageHousePrice }})
