Dobrą praktyka jest też wskazanie od jakiej wartości zaczynamy liczenie tj. evenNumbers.reduce((item, x) => item + x, 0) - jeśli tablica byłaby pusta to przy Twoim rozwiązaniu będzie błąd (nie ma pierwszego elemntu), przy zaproponowanym przeze mnie będzie po prostu zwrócone 0 :)

Fixed Task 05. in the previous solution to the task, I did not use the filter() and reduce() methods.
