Object access	138922.2 Ops/sec
Array find	50318.6 Ops/sec

Script Preparation code:

var items = Array.from(Array(100), (_,x) => ({key: x, value: x*10}));

var objContainer = {};
var arrContainer = [];

for (let i = 100; i >= 0; i--) {
  const index = Math.floor(Math.random() * 100);
  const item = items[index];
  objContainer[item.key] = item;
  arrContainer.push(item)
}

Tests:

Object access
items.forEach(item => objContainer[item.value])
Array find
items.forEach(item => arrContainer.find(containerItem => containerItem.value === item.value))
