Script Preparation code:

var arr = [];
for (var i = 0; i < 12345; i++) {
  
  	arr[i] = {x: "tset", i: i};
}

Tests:

map filter
filterMap = arr.filter(item => item.i % 2 === 0).map(item => item.x);
reduce
reduce = arr.reduce((acc, item) => { if(item.i % 2 === 0){ acc.push(item.x); } return acc; }, []);
