How to create new product with properties?

Question

I want to create a new "product" object and specify its properties (name, and etc), through the function "addProduct"

var storage = [
    {product: {name: "cat", count: 3443, price: 1000}}
    
];

function addProduct(newProduct) {
    var newProduct =  this.product;
}
var addProd = new addProduct("dog", 1488, 2000);

Here is one way to do it if I understood your correctly:

var storage = [
    {product: {name: "cat", count: 3443, price: 1000}}
    
];

function addProduct(newProduct) {
    storage.push(newProduct);
    console.log(storage);
}

addProduct({name: "dog", count: 1488, price: 2000});

Are you talking about creating objects with "constructor" ?

function Product(name, count, price) {
  this.name = name;
  this.count = count;
  this.price = price;
}

var product = new Product("dog", 1488, 2000);

console.log(product) // { name: "dog", count: 1488, price: 2000 }

You can either addProduct or updateProduct using below code:

var storage = [
    {product: {name: "cat", count: 3443, price: 1000}}

];

function addProduct(newProduct) {
    storage.push(newProduct)
    return true;
}

function updateProduct(prodLoc, updatedProduct) {
    storage[prodLoc] = updatedProduct;
    return true;
}

console.log(addProduct({"dog", 1488, 2000}));
console.log(updateProduct(0, {"updateDog", 1466, 1999}));
