Benchmark: random Object.hasOwnProperty vs Object in vs Object[] vs Array.indexOf vs Array.includes vs Set.has

Script Preparation code:

var object = {},
    array = [],
    set = new Set();
let i;
  
for (i = 0; i < 1000; i++) {
    object['something' + i] = true;
    array.push('something' + i);
    set.add('something' + i);
}

Tests:

Object.hasOwnProperty
object.hasOwnProperty('something' + Math.floor(Math.random() * 1000))
Object in
('something' + Math.floor(Math.random() * 1000)) in object
Array.indexOf
array.indexOf('something' + Math.floor(Math.random() * 1000)) !== -1
direct
object['something' + Math.floor(Math.random() * 1000)]
Array includes
array.includes('something' + Math.floor(Math.random() * 1000))
Set has
set.has('something' + Math.floor(Math.random() * 1000))
