我的for循环有没有更好更短的方法？

// 原始 for 循环
const arr = [1, 2, 3, 4, 5];
let result = [];
for (let i = 0; i < arr.length; i++) {
  result.push(arr[i] * 2);
}

// 使用 map 优化
const resultOptimized = arr.map(item => item * 2);

const arr = [1, 2, 3, 4, 5];
let result = [];
for (const item of arr) {
  result.push(item * 2);
}

const arr = [1, 2, 3, 4, 5];
let result = [];
arr.forEach(item => {
  result.push(item * 2);
});

function* generateNumbers(n) {
  for (let i = 0; i < n; i++) {
    yield i;
  }
}

const result = [];
for (const num of generateNumbers(5)) {
  result.push(num * 2);
}

// main.js
const worker = new Worker('worker.js');
worker.postMessage([1, 2, 3, 4, 5]);
worker.onmessage = function(event) {
  console.log(event.data); // [2, 4, 6, 8, 10]
};

// worker.js
self.onmessage = function(event) {
  const arr = event.data;
  const result = arr.map(item => item * 2);
  self.postMessage(result);
};
