javascript - 如何使用多个键按对象的值对对象进行排序？

Question

I want to use the sort method explained here但我有

{
  "CYLINDER": 2986,
  "HYDRAULIC": 1421,
  "JACKS": 84,
  "INSTALLATION": 119,
  "REAR": 61,
  "JACK": 334,
  "TUBE": 1,
  "FEED": 114,
  "ASSEMBLY": 326,
  "DCS": 2,
  "TOWER": 65,
  "RAISING": 8,
  "BREAKOUT": 6,
}

我创建了这个函数，将每个字符串分组在一起并添加一个计数(作为键的值，见上文)

function generateCountDuplication(wordArray) {
  const countedWords = wordArray.reduce(function(allWords, word) {
    if (word in allWords) {
      allWords[word]++;
    }
    else {
      allWords[word] = 1;
    }
    return allWords;
  }, {});
  return countedWords;
}

我尝试在 Stackoverflow 上进行谷歌搜索和查看，但没有找到当键不唯一时按值排序的任何位置。有什么线索可以解决吗？

我想要这样的结果:

{
  "TUBE": 1,
  "DCS": 2,
  "BREAKOUT": 6,
  "RAISING": 8,
  "REAR": 61,
  "TOWER": 65,
  "JACKS": 84,
  "FEED": 114,
  "INSTALLATION": 119,
  "ASSEMBLY": 326,
  "JACK": 334,
  "HYDRAULIC": 1421,
  "CYLINDER": 2986
}

按如下方式取消Object.keys()和map即可达到预期结果。

const list = {
  "CYLINDER": 2986,
  "HYDRAULIC": 1421,
  "JACKS": 84,
  "INSTALLATION": 119,
  "REAR": 61,
  "JACK": 334,
  "TUBE": 1,
  "FEED": 114,
  "ASSEMBLY": 326,
  "DCS": 2,
  "TOWER": 65,
  "RAISING": 8,
  "BREAKOUT": 6,
};

var newList = {};
Object.keys(list).sort(function(a,b){return list[a]-list[b]})
                 .map(key => newList[key] = list[key]);
console.log(newList);
