<!--your preparation HTML code goes here-->

Script Preparation code:

function generateTestArray() {
  const result = [];
  for (let i = 0; i < 1000000; ++i) {
    result.push(i);
  }
  return result;
}
var array = generateTestArray()

Tests:

forEach
var store = {}; array.forEach((elm) => { store[elm] = true; });
map
var store2 = {}; array.map((elm) => { store2[elm] = true; });
for of
var store3 = {}; for(const elm of array){ store3[elm] = true; }
for in
var store4 = {}; for(const index in array){ store4[array[index]] = true; }
reduce
array.reduce((acc, curr) => ({...acc,[curr]: true }), {});
