Benchmark: Array find vs Map get fixed

Script Preparation code:

var list = [{
	id: "a",
  name: "asd",
  age: 12,
  isValid: false,
},
 {
	id: "b",
  name: "bsd",
  age: 12,
  isValid: false,
},
 {
	id: "c",
  name: "c",
  age: 12,
  isValid: false,
},
             {
	id: "d",
  name: "dsd",
  age: 12,
  isValid: false,
},
             {
	id: "e",
  name: "esd",
  age: 12,
  isValid: false,
},
                          {
	id: "f",
  name: "fsd",
  age: 12,
  isValid: false,
},
                          {
	id: "g",
  name: "gsd",
  age: 12,
  isValid: false,
},
                          {
	id: "h",
  name: "hsd",
  age: 12,
  isValid: false,
},
                          {
	id: "i",
  name: "isd",
  age: 12,
  isValid: false,
},];

var map = new Map();
list.forEach((obj) => {
  map.set(obj.id, obj);
});

var id = "e";

Tests:

Array
const foundObj = list.find((obj) => obj.id === id); foundObj.isValid = true;
Map
const foundObj2 = map.get(id); foundObj2.isValid = true;
