javascript - 在多维数组中选择具有最高值的对象

Question

我试图找到选择具有最高特定属性值（在本例中为错误答案的数量）并返回另一个属性（名称）的对象的最佳方法。EG 以下对象应返回 Mark：

[
{name: "Henry", age: "NYN", attempts: 3, wrong: 2},
{name: "Mark", age: "NNNY", attempts: 4, wrong: 3},
{name: "Beth", age: "", attempts: 0, wrong: 0},
{name: "Sally", age: "YYNY", attempts: 4, wrong: 1},
]

解决这个问题的最佳方法是什么（在 JavaScript 中）？谢谢你的帮助！

Answer 1

这是一个简单的方法：

var objArray=[
{name: "Henry", age: "NYN", attempts: 3, wrong: 2},
{name: "Mark", age: "NNNY", attempts: 4, wrong: 3},
{name: "Beth", age: "", attempts: 0, wrong: 0},
{name: "Sally", age: "YYNY", attempts: 4, wrong: 1},
];
function getNameOfMostWrong(){
  //Set first object in array for most wrong as default
  var mostWrongPerson=objArray[0];
  for(var person in objArray){
    if(objArray[person].wrong > mostWrongPerson.wrong){
      mostWrongPerson=objArray[person];
    }
  }
  return mostWrongPerson.name;
}
