javascript - 如果值不满足给定条件，如何将其他数组元素包含到新数组中

Question

我这里有 1 个数组。如何在 JavaScript 中执行此逻辑

费率列表示例:

  var rates : [ 
   {id:1,value:7},  
   {id:2,value:7},
   {id:3,value:7},
   {id:4,value:6},
   {id:5,value:6},
   {id:6,value:5},
   {id:7,value:4},
  ]

条件是获得前5名的评分。最高为 7 .. 如果 7 小于 5 则包括比率 6 。如果所有费率小于 5。请包括费率 5。

注意:如果速率 7 小于 5 。所有速率可以大于5。参见其他场景

预期输出

{id:1,value:7},  
  {id:2,value:7},
  {id:3,value:7},
  {id:4,value:6},
  {id:5,value:6},

其他场景

 var rates : [ 
       {id:1,value:7},  
       {id:2,value:7},
       {id:3,value:7},
       {id:4,value:7},
       {id:5,value:5},
       {id:5,value:5},
       {id:5,value:5},
       {id:6,value:4},
       {id:7,value:4},
      ]

输出

{id:1,value:7},  
{id:2,value:7},
{id:3,value:7},
{id:4,value:7},
{id:5,value:5},
{id:5,value:5},
{id:5,value:5},

非常感谢您的帮助

这是您问题的伪代码答案:

/*Sort the rates highest to lowest by value*/

/*Create a new array to store your top rates*/

/*iterate over your rates */

    /* If there are less than 5 topRates go ahead and add the rate
       to top rates. 
       Remember rates is now sorted highest to lowest value
    */

    /* else if we have the top 5 already, check to see if
       the current rate is equal to the last top rate
    */

    /* otherwise our topRates has more than 5 and the next rate is 
       not the same value of our last top rate break out of the loop
    */
