how change variable in reduce function

[lalo4ka]

is possible change dynamically the variable in reducer function? reducer: (sum, item) => sum + item.count

Yes, you can set the reducer prop of the component to a method that will reduce values depending on whatever you want. Here is an example of what you could do :

data: {
  reduceAttr: 'count' // Can be set to 'sum', 'average' or 'count' by the user
},
methods: {
  reduce: function(sum, item) {
    return sum + item[this.reduceAttr]
  }
}
