Script Preparation code:

var length = 2000;

const array = Array(length);
for (let i = 0, { length } = array; i < length; i += 1) {
  array[i] = i;
}

function push() {
  var a = [];
  for (let i = 0; i < length; i += 1) {
    if (i % 2) {
     a.push(i);
    }
  }
  return a;
}

function append() {
  var a = Array(length);
  var offset = 0;
  for (let i = 0; i < length; i += 1) {
    if (i % 2) {
      a[offset++] = i;
    }
  }
  a.length = offset;
  return a;
}

function filter() {
	return array.filter((v) => v % 2);
}

Tests:
