Benchmark: Object.hasOwnProperty vs Object in vs Object[] vs Array.indexOf vs Array.includes123123

Script Preparation code:

  var object = {},
      array = [],
      i, test = 1000;
  
  for (i = 0; i < 1000; i++) {
   object['something' + i] = true;
   array.push('something' + i);
  }

  var object = {},      array = [],      i, test = 1000;    for (i = 0; i < 1000; i++) {   object['something' + i] = true;   array.push('something' + i);  }

Tests:

Object.hasOwnProperty
object.hasOwnProperty('something' + test)
object.hasOwnProperty('something' + test)
Object in
('something' + test) in object
('something' + test) in object
Array.indexOf
array.indexOf('something' + test) !== -1
array.indexOf('something' + test) !== -1
direct
object['something' + test] === true
object['something' + test] === true
Array includes
array.includes('something' + test)
array.includes('something' + test)
has
object.hasOwn('something' + test)
object.hasOwn('something' + test)
