Question

我正在为javascript Node JS中的拼字游戏评分程序编写算法，并试图使用创建具有函数作为值的对象。该函数调用并使用另一个函数，但是由于任何原因它都未定义我的函数。

我尝试在Google上搜索没有运气的解决方案。

//this is the original score key

const oldScoreKey = {
  1: ['A', 'E', 'I', 'O', 'U', 'L', 'N', 'R', 'S', 'T'],
  2: ['D', 'G'],
  3: ['B', 'C', 'M', 'P'],
  4: ['F', 'H', 'V', 'W', 'Y'],
  5: ['K'],
  8: ['J', 'X'],
  10: ['Q', 'Z']
};

//below is a transform function that reverses the keys and values of oldScoreKey

function transform(obj) {
  const newScoreKey = {};
  for (var key in oldScoreKey) {
    for (let i = 0; i < oldScoreKey[key].length; i++) {
      newScoreKey[oldScoreKey[key][i].toLowerCase()] = +key;
    }
  }
  return newScoreKey;
}

let newScoreKey = transform(oldScoreKey);

//below is the new object that has the scoreFunction key that is causing the problem.

let scrabbleScoring = {
  name: 'Scrabble',
  description: 'The traditional scoring algorithm.',
  scoreFunction: function(word) {
    var letter, i, sum = 0;
    for (i = 0; i < word.length; i++) {
      letter = word[i];
      sum += newScoreKey[letter];
    }
  }
};

console.log(scrabbleScoring.scoreFunction('word'))

对于scoreFunction中输入的任何单词，预期结果都是如此，根据{{1}}列出的分数系统进行评分。但是我收到一条错误消息，说明在尝试调用newScoreKey时newScoreKey是未定义的。

我试图在调用并使用另一个函数的对象中创建一个函数
