How to use $t from vue-i18n inside Vuex store to initialize static strings - vue.js

Question

In my vuex store module I have provinceData to supply as datasource for Vuetify dropdown selection box.
provinceData: [
{value:"AB", text: "Alberta"},
{value:"BC", text: "British Columbia"},
...
],
I can import i18n from '../plugins/i18n' and confirm in console output that i18n.t('province.BC') return me proper text from resource files
i18n.t('province.BC') British Columbia
click onLanguageChange fr
i18n.t('province.BC') British Columbia (Fr)
But how I can insert these translations into datasource?
provinceData: [
{value:"AB", text: ???i18n.t('province.AB')??? },
{value:"BC", text: ???i18n.t('province.BC')??? },
...
]
Now I realized what mistake I did by wrapping i18n.t('province.AB') into back ticks. Here is corrected version which render english only messages:
provinceData: [
{value:"AB", text: i18n.t('province.AB') },
{value:"BC", text: i18n.t('province.BC') },
...
]
Moreover, will it be reinitialized if I switch the current locale?
PS. When getter for this datasource is hit I can see that message retrieved according to current locale. But dropdown box izn't reloaded. That's the problem
Following getter print correct translation every time it called:
provinceData: (state) => {
console.log("i18n.t('province.BC')",i18n.t('province.BC'));
return state.provinceData;
},

Answer 1

Because the provinceData inside the store it can't be modified by anything but mutators.
So I decided to create this array right in the getter and it turns out to be quite fast.
provinceData: ( state ) =>
{
const provinceData = [ "AB", "BC", "MB", "NB", "NF", "NT", "NS", "NU", "ON", "PE", "QC", "SK", "YT" ];
let provinces = [];
provinceData.forEach( (province) => {
provinces.push
({
value : province,
text : i18n.t( 'province.'+province )
})
})
return provinces;
}
