Tell us what’s happening:

here is my problem
8. addProduct({name: “FLOUR”, quantity: 5}) should log flour quantity updated when an object having name equal to “flour” is found in the inventory array.

how to solve this?

Your code so far

let inventory = [];

function findProductIndex(productName) {
  const lowerName = productName.toLowerCase();

  return inventory.findIndex(product => product.name === lowerName);
}

function addProduct(product) {
    const index = findProductIndex(product.name);

    if(index !== -1) {
      inventory[index].quantity += product.quantity;
      console.log(inventory[index].name + " " + inventory[index].quantity);
      console.log(inventory[index].name) + " quantity updated";
    } else {
      product.name = product.name.toLowerCase();

      inventory.push(product);

      console.log(`${product.name} added to inventory`);
    }
}

function removeProduct(productName, quantity) {
  const index = findProductIndex(productName);
  const lowerName = productName.toLowerCase();

  if(index === -1) {
    console.log(`${lowerName} not found`);
    return;
  }
    const currentProduct = inventory[index];

    if(currentProduct.quantity < quantity) {
      console.log(`Not enough ${currentProduct.name} available, remaining pieces: ${currentProduct.quantity}`)
    } else {
      currentProduct.quantity -= quantity;

      console.log(`Remaining ${currentProduct.name} pieces: ${currentProduct.quantity}`)

      if(currentProduct.quantity === 0) {
        inventory.splice(index, 1);
      }
    }
  }
