Benchmark: Cloning. - MeasureThat.net

Script Preparation code:

const size = 10000;
var obj = {};
var set = new Set();
var map = new Map();
var arr = [];

for (let i=0; i < size; i++) {
  const item = `item${i}`;
  obj[item] = true;
  set.add(item);
  map.set(item, true);
  arr.push(item);
 
}

Tests:

obj
let copy = {...obj} delete copy.item5000
set
let copy = new Set(set) copy.delete("item5000")
map
let copy = new Map(map) copy.set("item5000", undefined);
array
let copy = [...arr] copy[5000] = undefined;
