Script Preparation code:

var items = Array.from(Array(1000), (_,x) => ({key: x, value: x*10}));

var objContainer = {};
var arrContainer = [];

for (let i = 100; i >= 0; i--) {
  const index = Math.floor(Math.random() * 1000);
  const item = items[index];
  objContainer[item.key] = item;
  arrContainer.push(item)
}

Tests:

Object Access
objContainer[88]
Array Find
arrContainer.find((e) => e === 88)
Array Filter
arrContainer.filter((e) => e === 88)
