// Problem Statement: Write a function called calculatePrice that prompts the user for two inputs: price and discount.
//  If the user doesn't provide a discount (i.e., leaves it blank), the function should apply a default discount of 10%.
//  If the user provides an invalid price or discount (e.g., a negative number or non-numeric input), it should display
// an error message and prompt them to try again.

// Finally, the function should calculate and return the final price after applying the discount.

// Requirements:

// Use default parameters for the discount. Validate both inputs to ensure they are positive numbers.

// function calculatePrice() {
//   let price = +prompt("please, enter the price :");
//   let discout = +prompt("please, enter discout too :");

//   if (price < 0 || typeof price != typeof 1) {
//     price = +prompt("ERROR, price type again :");
//   } else if (discout < 0 || typeof discout != typeof 1) {
//     discout = +prompt("ERROR, discount type again :");
//   }

//   if (discout == null || discout == "") {
//     discout = 10;
//   }

//   let finalPrice = (discout / 100) * price;
//   return finalPrice;
// }

// console.log(calculatePrice());
