object in vs array some/w includes vs array some/w indexOf (v3)

Revision 3 of this benchmark created on

Setup

const datas = [];
for(let i=0; i<300000; i++){
	if (i % 5 === 0) {
		datas[i] = { hoge: i+1 };		
	} else {
		datas[i] = { uuid: i+1, major: i+1, minor: i+1 };
	}
};
const keys = ['uuid', 'major', 'minor'];
