Performance Test filter vs if

var object = [
  {
    name: "a",
    expired: false
  },
  {
    name: "b",
    expired: true
  },
  {
    name: "c",
    expired: false
  },
  {
    name: "d",
    expired: true
  }
];

const functionTwo = () => {
  object
    .filter(o => o.expired)
    .forEach(() => {
      1 + 1;
    });
};

const functionOne = () => {
  object.forEach(o => {
    if (!o.expired) {
      return;
    }
    1 + 1;
  });
};

var iterations = 1000000;
console.time("Function #1");
for (var i = 0; i < iterations; i++) {
  functionOne();
}
console.timeEnd("Function #1");

console.time("Function #2");
for (var i = 0; i < iterations; i++) {
  functionTwo();
}
console.timeEnd("Function #2");

It's also worth having in mind that filter will create a new array, so potentially it causes GC time consumption too.
