const SETTING = {
  name : "LUCKY LOTTO!",

  maxNumber : 45,
}

const { count, maxNumber } = SETTING;
const lotto = new Set();

let result;
        
function getRandomNumber(maxNumber) {
   // 랜덤한 유일한 숫자값을 추출

  while (lotto.size < count ) {
    let number = Math.floor(Math.random()*maxNumber + 1);
    lotto.add(number);
  }   
 
  result = Array.from(lotto);
  return console.log(result);
}

getRandomNumber(maxNumber);
