How to do the multiplication with array objects

Question

How to do the multiplication with array objects and get the all 3 outputs

const size = [
  { hight: 20, width: 23, length: 54 },
  { hight: 40, width: 43, length: 44 },
  { hight: 20, width: 23, length: 54 },
];
const total = (size) => {
  const totalvalue = size.hight * size.width * size.length;
};    
console.log(total)

Answer 1

You can use Array.prototype.map.

const size = [
  { hight: 20, width: 23, length: 54 },
  { hight: 40, width: 43, length: 44 },
  { hight: 20, width: 23, length: 54 },
];

 const total = (size) => {
  const totalvalue = size.hight * size.width * size.length;
  return totalvalue; 
};

console.log(size.map(total))

Answer 2

You'll have to loop through the array. Something like:

const size = [
    { hight: 20, width: 23, length: 54 },
    { hight: 40, width: 43, length: 44 },
    { hight: 20, width: 23, length: 54 },
];
const total = row => row.total = row.hight + row.width + row.length;
size.forEach(total);

console.log(size);

Answer 3

You can make use of the reduce function

var sum = array.reduce(function(pv, cv) { return pv + cv; }, 0);
