[Vuejs]-How to retrieve value of key from an object inside an array

Why you are trying to console.log this.merchants in computed property. Check for computed property of vuejs here.

Your data is empty before data from API call even come. So that’s why your this.merchants is empty.

You can get you this.merchants value by using a method and run it after your api call or watching that like this:

watch: {
  merchants: function () {
    console.log(this.merchants)
  }
}

It will console this.merchants array everytime a change happens in it.
