Benchmark: dsadsa - MeasureThat.net

Script Preparation code:

var arr = [];
var ms = new Map();
var obj = {};
var i = 0;

while (i <= 1E5) {
  arr[i] = i;
  ms.set(i, i);
  obj[i] = i;
  i++;
}

Tests:

Array.find
const item = arr.find(item => item == 1E5);
Array.indexOf
const index = arr.indexOf(1E5);
Map.has
ms.has(1E5 - 1);
Object.hasOwnProperty
obj.hasOwnProperty(1E5-1);
