It is displayed as an array, how to remove brackets and quotes?

Question

Vue.js

Hello, there is a code:

selectedItemsSize: function () {
      return this.products.filter(function (item) {
        return this.sizes.includes(item.size);
      }, this);
    },

and in the template for the output of the result:
{{ sizes }}

When clicking on the checkbox, I use this code to display what sizes were selected. Output example:
[ "M", "L", "XL"]
And empty brackets are also initially shown []

How to remove these brackets and quotes?

What's up with Vue? You display an array - you are shown an array.
If you want to have a string - make a string from the array. At least through .toString(), or somehow more specifically.
