解法

function isPangram(string){
  const alphabet = 'abcdefghijklmnopqrstuvwxyz';
  const lowerString = string.toLowerCase();

  for (let char of alphabet) {
    if (lowerString.indexOf(char) === -1) {
      return false;
    }
  }
  return true;
}

筆記

使用for...ofalphabet一個一個拿出來比對
判斷是否存在 如果不存在就回傳false
跑完如果沒問題就回傳true

lowerString.indexOf(char) === -1
indexOfchar
=== -1相等於 沒找到(false)的意思


#javascript #Codewars #indexOf #for...of
