Tips for iterating through a nested JSON response using Vue.js

Recently, I started exploring Vue JS and encountered a challenge while looping through API responses using v-for. Below is the snippet from my code:

Get Coins Data

<div v-for="coin in coinsData">{{coinsData.data.coins.name}}</div>

This is how I implemented it in JavaScript:

 var app = new Vue({
        el: '#app',
        data: {
            coinsData: []
        },
        methods: {
    getCoinsData() {
      fetch("https://api.coinranking.com/v1/public/coins")
        .then(response => response.json())
        .then(data => (this.coinsData = data));
    }
  }
    })

The API response that needs to be looped through can be found at . It's pretty extensive, so I haven't included it here :)

To ensure you are getting the correct response property, call the method within a lifecycle hook such as created. Keep in mind that the coins property is located 3 levels deep in the response:

var vm = new Vue({
  el: '#app',
  data: {
    coinsData: []
  },
  methods: {
    getCoinsData() {
      fetch("https://api.coinranking.com/v1/public/coins")
        .then(response => response.json())
        .then(json => this.coinsData = json.data.coins);
    }
  },
  created() {
    this.getCoinsData();
  }
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <div v-for="coin in coinsData">{{ coin.name }}</div>
</div>
