有没有更优雅的方式来编写此行代码？

_.chain(_.uniqBy(someArray,"someProperty.name")).map("someProperty").value();

似乎我应该能够链接它,而不是将lodash .uniqBy调用嵌套在.chain调用中.

我希望以下内容能奏效,但不会.

_.chain(someArray).map("someProperty").value().uniqBy("name");

输入为：

someArray = [
   {
      aProp: '1',
      anotherProp: '2',
      thirdProp: '3',
      someProperty: {
          id: 1,
          name: "john"
      }
   },
   {
      aProp: '3',
      anotherProp: '4',
      thirdProp: '5',
      someProperty: {
          id: 1,
          name: "john"
      }
   },
   {
      aProp: '2',
      anotherProp: 'f',
      thirdProp: '6',
      someProperty: {
          id: 2,
          name: "tom"
      }
   },
   {
      aProp: 't',
      anotherProp: 'g',
      thirdProp: 'f',
      someProperty: {
          id: 3,
          name: "yacob"
      }
   },
];

输出应为：

[{id:1, name:"john"},{id:2, name:"tom"},{id:3, name:"yacob"}]

解决方法:

实际上,您在正确的轨道上：

_.chain(data).map('someProperty').uniqBy('id').value()
