Answer 1

Are you sure you have injected store to the component like this:

 let store = new Vuex.Store({
    state: {
    name: 'Alicia Vikander',
    age: 20,
    dob: '20/08/1990'
  },
  mutations: {
    updateName(state, name) => {
      state.name = name
    }
  }
})

new Vue({
  store,
  el: '#app',
  render: h => h(App)
});
