題目

Quarter of the year

解法:

第一版

const quarterOf = (month) => {
  if (month >= 1 && month <= 3) {
    return 1;
  } else if (month >= 4 && month <= 6) {
    return 2;
  } else if (month >= 7 && month <= 9) {
    return 3;
  } else {
    return 4;
  }
}

第二版:Math.ceil

const quarterOf = (month) => {
  return Math.ceil(month / 3);
}

筆記

第一版很簡單地解開
第二版想用Math語法,但忘了要用哪個
翻了一下MDN使用Math.ceil做無條件進位


#javascript #Codewars #Math.ceil
