javascript - lodash 深度嵌套数组过滤器

Question

我有一个像这样的复杂嵌套对象数组，我必须返回一个基于 attributeScore > 90 的新数组(过滤器)。我将如何使用 javascript .filter 或 lodash _.find() 或 _.some 函数来完成此操作？

trucks:[
     {wheels:[
             {name:"xyz",
              mechanics: [
                     {engine:'50cc',
                     attributeScore:100},
                     {....} ,{...}
                    ]
              },
              {name:"gcd",
              mechanics: [
                     {engine:'80cc',
                     attributeScore:90},
                     {....} ,{...}
                    ]
              }, 
            ,{...}
         ]}
         ,{...}
      ]

我尝试过这样的过滤器

const fil = trucks.filter(function(item) {
    return item.wheels.some(function(tag) {
      return tag.mechanics.some(function(ques){
        return ques.attributeScore <= 25;
      });
    });
  });

但它返回一个空数组。我预期的返回数组类型应该是

trucks:[
     {wheels:[
             {name:"xyz",
              mechanics: [
                     {engine:'50cc',
                     attributeScore:100},
                     {....} ,{...}
                    ]
              },
            ,{...}
         ]}
      ]

感谢任何帮助!!

现在就试试这个，

var fill = trucks.map(function(item) {
    return item.wheels.map(function(tag) {
      return tag.mechanics.filter(function(ques){
        return ques.attributeScore == 100;
      });
    });
  });
