Script Preparation code:
 
var myArr = Array.from({
    length: 16000
}, () => ({ someData: 123, value: Math.floor(Math.random() * 1000) }));
var myCopy = null;
Tests:
  • Lodash uniqBy

     
    myCopy = _.uniqBy(myArr, 'value').map(({ value }) => value);
  • new Map() Destructuring

     
    myCopy = [...new Map(myArr.map((el) => [el.value, el])).values()];
