Benchmark: Test on data for 2 years in months

Script Preparation code:

function generateTestArray() {
  const result = [];
  for (let i = 0; i < 24; ++i) {
    result.push({
      a: i,
      b: i / 2,
      c: i * 2,
    });
  }
  return result;
}

Tests:

.forEach
const array = generateTestArray(); const newArr = [] array.forEach((x) => { newArr.push(x.a % 2 === 0 ? x : {d: x.a, e: x.b, f: x.c}) });
for..of
const array = generateTestArray(); const newArr = [] for(const x of array) { newArr.push(x.a % 2 === 0 ? x : {d: x.a, e: x.b, f: x.c}) }
.map
const array = generateTestArray(); array.map(x => x.a % 2 === 0 ? x : {d: x.a, e: x.b, f: x.c})
.map (destructuring)
const array = generateTestArray(); array.map(({a,b,c}) => a % 2 === 0 ? {a, b, c} : {d: x.a, e: x.b, f: x.c})
.for (init array)
const array = generateTestArray(); const newArr = [] for (let i = 0; i < array.length; ++i) { newArr.push(array[i].a % 2 === 0 ? array[i] : {d: array[i].a, e: array[i].b, f: array[i].c}) }
.reduce
const array = generateTestArray(); array.reduce((p, x) => p.push(x => x.a % 2 === 0 ? x : {d: x.a, e: x.b, f: x.c}), []);
