Vuex namespaced getters with parameter

Vuex getter is not reactive .

In the previous Vuex tutorial, we learned that by default, getters, actions, and mutations inside modules are registered under the global namespace, which allows multiple modules to react to the same mutation or action .

Getters are a part of Vuex store and they are used to calculate data based on store state . … They cache data and smartly update themselves when the state changes; They can return functions, so that it’s possible to pass additional arguments to calculate data based on them.
