      return -1
    }

function addProduct(product) {
    product.name = product.name.toLowerCase();
    
    const index = findProductIndex(product.name);
    
    if (index !== -1) {
        inventory[index].quantity += product.quantity;
        console.log(`${product.name} quantity updated`);

    const lowercaseName = productName.toLowerCase();
    const index = findProductIndex(lowercaseName);
    
    if (index === -1) {
        console.log(`${lowercaseName} not found`);
        return;
    }
    
    const product = inventory[index];
    
    if (product.quantity < quantity) {
        console.log(`Not enough ${product.name} available, remaining pieces: ${product.quantity}`);
        return;
    }
    
    product.quantity -= quantity;
    
    if (product.quantity === 0) {
  
        inventory.splice(index, 1);
        console.log(`Remaining ${product.name} pieces: 0 (removed from inventory)`);

You don’t need an else statement in your findProductIndex function. Put the return statement for -1 outside the for loop and your code should pass.
