const initialValue = 0;
const numbers = [5, 10, 15];
const reducer = (accumulator, item) => {
return accumulator + item;
};
const total = numbers.reduce(reducer, initialValue)

arr.reduce(callback( accumulator, currentValue[, index[, array]] )[, initialValue])
Example 5: array reduce

}[, initialValue]);
