Benchmark: reduce vs filter+map on one million

Script Preparation code:

var items = [];
for (var i = 0; i < 1000000; i++) {
  items[i] = {
    id: i,
    selected: i % 4 == 0
  };
}

Tests:

reduce
items.reduce( ( array, item ) => { if ( item.selected ) { array.push( item.id ); } return array; }, [] );
filter+map
items.filter( x => x.selected ).map( x => x.id );
