//01 transform
var data = [15, 3, 20];

var reducer = function(accumulator, item) {

};

var initialValue = 0;

var total = data.reduce(reducer, initialValue);

basic example
var data = [30, 5],
    initialValue = 0;
    reducer = function(accumulator, initialValue){
      return accumulator + initialValue;
    }

var newData = data.reduce(reducer, initialValue);
console.log('new data is', newData);
