如何从Java项目运行Docker容器？(How to run Docker container from Java project?)

 您可以尝试这种纯JS方法： 
 
 
 
 
 
  
let obj = [{'vote':999,'name':'D'},{'vote':341,'name':'A'},{'vote':789,'name':'A'},{'mid':555,'name':'B'}]
let result = [];
obj.reduce(function(p, c){
  if(p[c.name] === undefined){
    result.push(c);
    p[c.name] = c.vote;
  }
  else if(c.vote > p[c.name]){
    let o = result.find(x=> x.name === c.name);
    o.vote = c.vote
  }
  return p;
}, {});

console.log(result)
 
 
 
 
 
 
 Lodash方法 
 
 逻辑 
 
 
 
 按name升序排序数组，按vote降序排序。 
 
 
 现在使用_.uniqBy因为它会选择第一次出现。 
 
 
 注意：我无法使用lodash（ 4.17 ）进行排序（没有太多使用它），所以我使用纯JS来对它进行排序。 
 
 Lodash 4.17 
 
 正如@ Ori Drori正确指出的那样 ，我们应该使用_.sortedUniqBy而不是_.uniqBy因为它针对排序数组进行了优化。 
 
 
 
 
 
  
let obj = [{'vote':999,'name':'D'},{'vote':341,'name':'A'},{'vote':789,'name':'A'},{'mid':555,'name':'B'}]

var sortedArray = obj.sort(function(a,b){
  return a.name.localeCompare(b.name) || b.vote - a.vote
});

var result = _.sortedUniqBy(sortedArray, 'name');
console.log(result)
 
  
<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.min.js"></script>
 
 
 
 
 
 
 Lodash 3.10 
 
 
 
 
 
  
let obj = [{'vote':999,'name':'D'},{'vote':341,'name':'A'},{'vote':789,'name':'A'},{'mid':555,'name':'B'}]

var result =_.uniq(
              _.sortByOrder(
                obj, 
                ["name", "vote"], 
                ["asc", "desc"]
              ), "name");
console.log(result)
 
  
<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/3.10.0/lodash.min.js"></script>
 
 
 
 

You can try this pure JS approach:
 
 
 
 
 
  
let obj = [{'vote':999,'name':'D'},{'vote':341,'name':'A'},{'vote':789,'name':'A'},{'mid':555,'name':'B'}]
let result = [];
obj.reduce(function(p, c){
  if(p[c.name] === undefined){
    result.push(c);
    p[c.name] = c.vote;
  }
  else if(c.vote > p[c.name]){
    let o = result.find(x=> x.name === c.name);
    o.vote = c.vote
  }
  return p;
}, {});

console.log(result)
 
 
 
 
 
 
Lodash approach
 
Logic
 
 
 
Sort array in ascending order by name and descending order by vote.
 
 
Now use _.uniqBy as it will pick first occurrence.
 
 
Note: I was unable to sort using lodash (4.17) (have not used it much), so I have use pure JS to sort it.
 
Lodash 4.17
 
As correctly pointed by @Ori Drori, we should use _.sortedUniqBy instead of _.uniqBy as it is optimised for sorted arrays.
 
 
 
 
 
  
let obj = [{'vote':999,'name':'D'},{'vote':341,'name':'A'},{'vote':789,'name':'A'},{'mid':555,'name':'B'}]

var sortedArray = obj.sort(function(a,b){
  return a.name.localeCompare(b.name) || b.vote - a.vote
});

var result = _.sortedUniqBy(sortedArray, 'name');
console.log(result)

let obj = [{'vote':999,'name':'D'},{'vote':341,'name':'A'},{'vote':789,'name':'A'},{'mid':555,'name':'B'}]

var result =_.uniq(
              _.sortByOrder(
                obj, 
                ["name", "vote"], 
                ["asc", "desc"]
              ), "name");
console.log(result)
