Benchmark: Object direct vs Array.indexOf vs Array.find vs Map.has

Script Preparation code:

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

Tests:

direct
object['something' + test] === true
Array.indexOf
array.indexOf({id:'something' + test}) !== -1
Array find
array.find(e => e.id === 'something' + test)
Map has
map.get('something' + test)
