js map 跳出循环

const array = [1, 2, 3, 4, 5];
const newArray = [];

for (let i = 0; i < array.length; i++) {
  if (array[i] === 3) break; // 当元素为3时跳出循环
  newArray.push(array[i] * 2);
}

console.log(newArray); // 输出: [2, 4]

const array = [1, 2, 3, 4, 5];
const newArray = [];

array.forEach((element) => {
  if (element === 3) return; // 当元素为3时跳过当前迭代
  newArray.push(element * 2);
});

console.log(newArray); // 输出: [2, 4]

const array = [1, 2, 3, 4, 5];
const newArray = [];

array.some((element) => {
  if (element === 3) return true; // 当元素为3时终止遍历
  newArray.push(element * 2);
  return false;
});

console.log(newArray); // 输出: [2, 4]

const array = [1, 2, 3, 4, 5];
const newArray = [];

array.every((element) => {
  if (element === 3) return false; // 当元素为3时终止遍历
  newArray.push(element * 2);
  return true;
});

console.log(newArray); // 输出: [2, 4]
