 let non_duplicated_data = _.uniqBy(pendingDeposits, v => [v.stellarAccount, v.externalTransactionId].join());

如果您只需要通过对象的一个字段进行比较，则可以使用Array迭代方法执行此操作：

    function uniq(a, param){
        return a.filter(function(item, pos, array){
            return array.map(function(mapItem){ return mapItem[param]; }).indexOf(item[param]) === pos;
        })
    }

    uniq(things.thing, 'place');

为懒惰的Typescript开发人员提供快速（运行时更少）和类型安全的答案：

export const uniqueBy = <T>( uniqueKey: keyof T, objects: T[]): T[] => {
  const ids = objects.map(object => object[uniqueKey]);
  return objects.filter((object, index) => !ids.includes(object[uniqueKey], index + 1));
} 

您可以将数组对象转换为字符串，以便对其进行比较，将字符串添加到集合中，以便自动删除可比较的重复项，然后将每个字符串转换回对象。

它可能不像其他答案那样有表现力，但它是可读的。

const things = {};

things.thing = [];
things.thing.push({place:"here",name:"stuff"});
things.thing.push({place:"there",name:"morestuff"});
things.thing.push({place:"there",name:"morestuff"});

const uniqueArray = (arr) => {

  const stringifiedArray = arr.map((item) => JSON.stringify(item));
  const set = new Set(stringifiedArray);

  return Array.from(set).map((item) => JSON.parse(item));
}

const uniqueThings = uniqueArray(things.thing);

console.log(uniqueThings);

使用ES6“reduce”和“find”数组助手方法的简单解决方案

工作效率高，非常好！

"use strict";

var things = new Object();
things.thing = new Array();
things.thing.push({
    place: "here",
    name: "stuff"
});
things.thing.push({
    place: "there",
    name: "morestuff"
});
things.thing.push({
    place: "there",
    name: "morestuff"
});

// the logic is here

function removeDup(something) {
    return something.thing.reduce(function (prev, ele) {
        var found = prev.find(function (fele) {
            return ele.place === fele.place && ele.name === fele.name;
        });
        if (!found) {
            prev.push(ele);
        }
        return prev;
    }, []);
}
console.log(removeDup(things));

这里有另一种技术，可以找到重复的数量，并轻松地从数据对象中删除它。“dupsCount”是重复文件数。首先对数据进行排序，然后删除。它将为您提供最快的重复删除。

  dataArray.sort(function (a, b) {
            var textA = a.name.toUpperCase();
            var textB = b.name.toUpperCase();
            return (textA < textB) ? -1 : (textA > textB) ? 1 : 0;
        });
        for (var i = 0; i < dataArray.length - 1; ) {
            if (dataArray[i].name == dataArray[i + 1].name) {
                dupsCount++;
                dataArray.splice(i, 1);
            } else {
                i++;
            }
        }
