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 valuesSet = new Set(myArr.map(({ value }) => value)); myCopy = myArr.filter(({ value }) => valuesSet.has(value));
map and filter index
const valuesArr = myArr.map(({ value }) => value); myCopy = myArr.filter(({ value }, index) => valuesArr.indexOf(value) === index);
