javascript - Javascript 常用词

Question

我想从字符串中获取常用单词。

我发现了这个方法: http://jsbin.com/nufimudivu/1/edit

for(var i = 0; i < words.length; i++) {
    wordCounts["_" + words[i]] = (wordCounts["_" + words[i]] || 0) + 1;
}

问题是我希望我的输出是这样的

{
   {
         'word': '_lipsum',
         'count': Number here
   }, 
   {
          <!-- other word here -->
   }
}

您可以简单地将输出转换为您想要的格式:

var wordArr = [];
for (var word in wordCounts) {
  wordArr.push({
    word: word,
    count: wordCounts[word]
  })  
}
console.log(wordArr)
