Task 1 Create a new array of objects based on the old array, with only the "brand" and "isDiesel" properties.

Copied! ✅ 📝 Copy Code ➕ Insert Code const newCars = cars.map((car) => { return { brand: car.brand, isDiesel: car.isDiesel } });

console.log(newCars); Task 2 Create a new array that includes only the cars with a diesel engine.

Copied! ✅ 📝 Copy Code ➕ Insert Code const dieselCars = cars.filter((car) => car.isDiesel); console.log(dieselCars); Task 3 Create a new array that includes only the cars without a diesel engine.

Copied! ✅ 📝 Copy Code ➕ Insert Code const nonDieselCars = cars.filter((car) => !car.isDiesel); console.log(nonDieselCars); Task 4 Calculate the total price of all non-diesel cars.

Copied! ✅ 📝 Copy Code ➕ Insert Code const sum = cars .filter((car) => !car.isDiesel) .map((car) => car.price) .reduce((acc, price) => acc + price, 0); console.log(sum); Task 5 Increase the price of all cars in the array by 20%.

Copied! ✅ 📝 Copy Code ➕ Insert Code cars.forEach((car) => car.price *= 1.2); console.log(cars); Task 6 Create a new array where all diesel cars are replaced with a new car object.

Copied! ✅ 📝 Copy Code ➕ Insert Code const cars2 = cars.map((car) => { if (car.isDiesel) { return { brand: "Tesla", price: 25000, isDiesel: false }; } return car; });

console.log(cars2); Alternatively:

Copied! ✅ 📝 Copy Code ➕ Insert Code const cars3 = cars.map((car) => car.isDiesel ? { brand: "Tesla", price: 25000, isDiesel: false } : car); Feel free to modify the README.md file according to your needs.
