.find	45.9 Ops/sec

Script Preparation code:

  var numberOfData = 1e3
    data = [];
    for (let i = 0; i <= numberOfData; i++) {
      data[i] = { test: `my-${numberOfData - i}` };
    }
data = _.shuffle(data);

Tests:

.map.includes
let arrayIds = data.map((el) => el.test); for (let i = 0; i <= numberOfData; i++) { arrayIds.includes(`my-${numberOfData - i}`); }
.find
for (let i = 0; i <= numberOfData; i++) { data.find((el) => el.test === `my-${numberOfData - i}`); }
