Benchmark: Usporedba - MeasureThat.net

Script Preparation code:

window.bigMap = {};
window.bigArray = Array.from({length: 100000}).map((_, index) => {
  const id = "person-id-" + index;
  const person = { id: id, name: `John Doe ${id}`, age: 18 + Math.floor(Math.random() * 70)  };
  bigMap[id] = person;
  return person
})

Tests:

Find person in map
const id = "person-id-" + Math.floor(Math.random() * 100000); const person = window.bigMap[id];
Find person in array
const id = "person-id-" + Math.floor(Math.random() * 100000); const person = window.bigArray.find(p => p.id === id);
