Substitute language variable in vue.js iteration?

Question

Vue.js

There is such an output in the template

<option   v-for="dish in  menu.dishes[1][0]" :value="dish.id"   v-bind:key="dish.id">{{dish.title_ru}}</option>

export default {

  data(){
    return {
      menu:{
        dishes:  '',
        selectedmenu:  '',
      },
      dates: '',
      personal:'',
      lang:'',
    }
  }

I will get the lang variable from the api.
{{dish.title_ru}} wanted instead of ru to substitute the value from the API for example en. How can I put a variable there?

Answer 1

{{ dish[`title_${lang}`] }}
