How does vue calculate the first item using computed?

computed calculates the data with an OrderItems index of 1

computed: {
    goodItem: {
      get() {
        // ?
        return this.goodsList;
      },
    },
},

getGoods() {
    this.goodsList = res.Data || [];
}

I think this is fine. Is there a problem

return this.goodsList[0];
