    <div>
      <h4>{{product.price}} UAH</h4>
    </div>
    <div>
      <h4>{{product.name}}</h4>
      <p v-html="product.description">{{product.description.substring(0,3)+".."}}</p>
    </div>

First of all - it's not array, it's object. If you need just to trim your string, you can use usual js string function - trim():

{{ product.description.trim() }}

Otherwise, if you need to cut your string due to max length you can use substr():

{{ product.description.substr(0, maxlength) }}
