需要帮助为新数组赋值，然后计算这些值

// 创建一个新数组
let newArray = [];

// 为新数组赋值
for (let i = 0; i < 10; i++) {
  newArray[i] = i + 1;
}

// 计算数组中的值
let sum = 0;
let product = 1;

for (let i = 0; i < newArray.length; i++) {
  sum += newArray[i];
  product *= newArray[i];
}

console.log("新数组的和为：" + sum);
console.log("新数组的乘积为：" + product);
