将Array划分为2个子数组，并检查乘法是否相等

function checkEqualProduct(arr) {
  var totalProduct = 1;
  for (var i = 0; i < arr.length; i++) {
    totalProduct *= arr[i];
  }

  var firstProduct = 1;
  var secondProduct = totalProduct;
  for (var j = 0; j < arr.length; j++) {
    firstProduct *= arr[j];
    secondProduct /= arr[j];
    if (firstProduct === secondProduct) {
      return true;
    }
  }

  return false;
}

// 示例用法
var array = [1, 2, 3, 4, 5, 6];
var result = checkEqualProduct(array);
console.log(result); // 输出 true
