parseInt() doubt

Hi there! I was looking for some more information in MDN about the parseInt function and I got dizzy. Why all this strings returns the number 15? parseInt('0xF', 16); parseInt('F', 16); parseInt('17', 8); parseInt(021, 8);

Or this ones returns the number 4? parseInt('0xF', 16); parseInt('F', 16); parseInt('17', 8); parseInt(021, 8);

Thank you for the time if somebody can explain it to me :)
