Benchmark: Associative object array VS array.find

Script Preparation code:

o = {};
a = [];

for (var i = 0; i<= 10000; i++){
	a.push({'id' : ''+i, 'name' : 'name_'+i, 'firstname' : 'firstname_'+i});
  	o[''+i] = {'id' : ''+i, 'name' : 'name_'+i, 'firstname' : 'firstname_'+i}
}

Tests:

Get index of object
name = o['1234'].name;
Get array.find
name = a.find(t => t.id == '1234');
