Tell us what’s happening:

  1. addProduct({name: “FLOUR”, quantity: 5}) should add 5 to quantity value of the object having name equal to “flour” in the inventory array.
  2. addProduct({name: “FLOUR”, quantity: 5}) should push {name: “flour”, quantity: 5} to the inventory array when no object having name equal to “flour” is found in the inventory.

I have problems with this two test, but it checking alll right< thanks for asttantion

Your code so far

let inventory = [];

function findProductIndex(name) {
   for (let i = 0; i < inventory.length; i++) {
     if(inventory[i].name.toLowerCase() === name.toLowerCase()) {
       return i;
     }
   }
   return -1;
}

function addProduct(product) {
  let index = findProductIndex(product.name);
  if (index > -1) {
    inventory[index].quantity = product.quantity;
    console.log(product.name.toLowerCase() + " " + "quantity updated");
  }else{
    inventory.push(product);
    console.log(product.name.toLowerCase() + " " + "added to inventory")
  }
}

let product1 = {name: "Amur", quantity: 5};
let product2 = {name: "flour", quantity: 5};
inventory.push(product1, product2)

console.log(findProductIndex("FLOUR"))
addProduct({name: "Kaka", quantity: 6});
addProduct({name: "FLOUR", quantity: 5})
addProduct({name: "FLOUR", quantity: 5})
console.log(inventory);

add this below your code:

inventory.length = 0;
inventory.push({name: 'flour', quantity: 15});
inventory.push({name: 'rice', quantity: 10});
inventory.push({name: 'sugar', quantity: 5});
addProduct({name: 'Flour', quantity: 5});
addProduct({name: 'RICE', quantity: 5});
addProduct({name: 'SuGar', quantity: 5});

console.log(inventory)

the final quantities should be 20 for flour, 15 for rice and 10 for sugar. Check the inventory at the end, does it have those values?

Story 2 says the findProductIndex function should always use the lowercase form of the product to perform the search. Are you doing this?

What is this doing:

inventory[index].quantity = product.quantity;

Story 1 says the object name should always be lowercase. Where is this in your else statement?
