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));
