javascript - Node : removing duplicate objects from array

Question

我有一个对象数组，我想删除重复的项目。下面讨论这个主题，但是 ES6 解决方案似乎不适用于对象: Unique values in an array

var myArray=[{fname:"Bob", sname:"Brown"},{fname:"Jill",sname:"White"},{fname:"Bob", sname:"Brown"}];
var unique = myArray.filter((v, i, a) => a.indexOf(v) === i);
/*
[ { fname: 'Bob', sname: 'Brown' },
  { fname: 'Jill', sname: 'White' },
  { fname: 'Bob', sname: 'Brown' } ]
*/
let unique = [...new Set(myArray)];
/*
[ { fname: 'Bob', sname: 'Brown' },
  { fname: 'Jill', sname: 'White' },
  { fname: 'Bob', sname: 'Brown' } ]
*/

使用 lodash 中的 _.uniqBy 或 _.uniqWith ;)

const _ = require('lodash');

const myArray=[{fname:"Bob", sname:"Brown"},{fname:"Jill",sname:"White"},{fname:"Bob", sname:"Brown"}];

console.log(_.uniqWith(myArray, _.isEqual));
