如何用Array.reduce方法求奇偶数之和？

const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9];

// 使用 reduce 方法计算奇数之和
const oddSum = numbers.reduce((accumulator, currentValue) => {
  return currentValue % 2 !== 0 ? accumulator + currentValue : accumulator;
}, 0);

// 使用 reduce 方法计算偶数之和
const evenSum = numbers.reduce((accumulator, currentValue) => {
  return currentValue % 2 === 0 ? accumulator + currentValue : accumulator;
}, 0);

console.log('Odd Sum:', oddSum); // 输出: Odd Sum: 25
console.log('Even Sum:', evenSum); // 输出: Even Sum: 20
