Benchmark: foreach: 2array vs object with keys vs object with values vs object with entries

Script Preparation code:

var arr = [];
var obj = {};

for (i = 0; i < 1000; ++i) {
  arr.push(i);
  obj[i] = i;
}

Tests:

array
arr.forEach( (item) => item, );
object with keys
Object.keys(obj).forEach( (key) => key, );
object with values
Object.values(obj).forEach( (value) => value, );
object with entries 1
Object.entries(obj).forEach( (entry) => entry, );
object with entries 2
Object.entries(obj).forEach( ([key, value]) => [key, value], );
