javascript array of arrays of objects code example

Example 1: create array of objects javascript

let products = [
  {
    name: "chair",
    inventory: 5,
    unit_price: 45.99
  },
  {
    name: "table",
    inventory: 10,

    unit_price: 399.50
  }
];
function listProducts(prods) {
  let product_names = [];
  for (let i=0; i<prods.length; i+=1) {
   product_names.push(prods[i].name);
  }
  return product_names;
}
console.log(listProducts(products));
function totalValue(prods) {
  let inventory_value = 0;
  for (let i=0; i<prods.length; i+=1) {
    inventory_value += prods[i].inventory * prods[i].unit_price;
  }
  return inventory_value;
}
console.log(totalValue(products));

Example 2: flatten array object javascript

var flattenArray = function(data) {
	return data.reduce(function iter(r, a) {
		if (a === null) {
			return r;
		}
		if (Array.isArray(a)) {
			return a.reduce(iter, r);
		}
		if (typeof a === 'object') {
			return Object.keys(a).map(k => a[k]).reduce(iter, r);
		}
		return r.concat(a);
	}, []);
}
console.log(flattenArray(data))

//replace data with your array
