如何从另一个JS数组创建新的JS数组

我想从一个对象创建新的 JS 数组。我解释了我的场景如下。

数组 1：

const arr1 = [
{CODE: "PPM", YARN: 1987, EXP: "IUYT", CARD: "MMN"},
{CODE: "SSW", YARN: 4500, EXP: "NBVC", CARD: "MMN"},
{CODE: "YTR", YARN: 0740, EXP: "NBVC", CARD: "MMN"},
{CODE: "NNH", YARN: 1540, EXP: "MHYT", CARD: "MMN"}
]


数组 2：

const arr2 = [
{PRICE: 6354, CODE: "SSW", WARN: "NBVC"},
{PRICE: 8637, CODE: "NNH", WARN: "MHYT"},
]


预期输出：

output = [
{CODE: "SSW", YARN: 4500, EXP: "NBVC", CARD: "MMN"},
{CODE: "NNH", YARN: 1540, EXP: "MHYT", CARD: "MMN"}
]


解释：

我想比较arr1和arr2。如果arr1.code包含arr2.code它应该在新数组中。这意味着arr1.code[2] = 'SSW'。SSW包含在arr2.code[0]. 然后arr1.code[2]应该在新数组中。对arr1.code[3] = 'NNH'. NNH包含在arr2.code[1].

试过的代码：

console.log(arr1.filter(({ CODE: code1 }) => arr2.some(({ CODE: code2 }) => code2 === code1));


当我尝试上面的代码时，我收到一个错误

渲染错误：“类型错误：无法读取未定义的属性‘价格’”

帮我解决这个问题。
