HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var myArr = Array.from({
    length: 16000
}, () => ({ value: Math.floor(Math.random() * 1000) }));

var myCopy = null;

Tests:

Lodash uniqBy path
myCopy = _.uniqBy(myArr, 'value');
Lodash uniqBy function
myCopy = _.uniqBy(myArr, obj => obj.value);
Map
myCopy = [...new Map(myArr.map(obj => [obj.value, obj])).values()]
Set and filter
const mySet = new Set(myArr.map({value}) => value)); myCopy = [...myArr.filter(obj => mySet.has(obj.value))];
uniq by filter
const mapMyArr = myArr.map(({ value }) => value); myCopy = myArr.filter((obj, index) => mapMyArr.indexOf(value) === index);
