Pin con expresiones regulares de codewars Regex validar código PIN

"Hola mundo", estoy tratando de resolver un problema de codewars y realmente estoy luchando con expresiones regulares. En primer lugar, quiero pedir disculpas si mi pregunta no está escrita correctamente o tal vez (pregunta tonta). Así que al grano

los códigos pin no pueden contener nada más que exactamente 4 dígitos o exactamente 6 dígitos y no símbolos como (-)

 if ((pin.match(/^[0-9]+$/) != null && pin.length === 4) || pin.length === 6) return true; else return false; } console.log(validatePIN("-12345"));// this should be false.It is true because it contains the "-" and length===6
