Remove Comma In The Last Element In Javascript Vuejs

I want to remove comma in the last element in Vue. But I dont know how to do that because the index of the last element is unknown. )}} </td>

I'd be tempted to move it to a computed though - keeps markup clean

<td v-if="category.sub_category.length > 0">
      {{subcats}}
</td>


computed: {
  subcats() {
    returnthis.category.sub_category.map(({subcategory_name}) => subcategory_name).join(', ');
  }
}

Solution 2:

elements.join(',')

You don't need to create a function for this just use it inside the Vue tag like this

{{elements.join(',')}}
