如何获得数组的最大乘积

function getMaxProduct(nums) {
  let maxProduct = nums[0];
  let maxPositive = nums[0];
  let minNegative = nums[0];

  for (let i = 1; i < nums.length; i++) {
    const num = nums[i];

    if (num > 0) {
      maxPositive = Math.max(num, maxPositive * num);
      minNegative = Math.min(num, minNegative * num);
    } else if (num < 0) {
      const temp = maxPositive;
      maxPositive = Math.max(num, minNegative * num);
      minNegative = Math.min(num, temp * num);
    } else {
      maxPositive = 0;
      minNegative = 0;
    }

    maxProduct = Math.max(maxProduct, maxPositive);
  }

  return maxProduct;
}

const nums = [2, 3, -2, 4];
const maxProduct = getMaxProduct(nums);
console.log("数组的最大乘积为：" + maxProduct);
