Vector cross product	594810f028c0303b75339ad2	5		矢量交叉产品

Description

矢量被定义为具有三个维度，由三个数字的有序集合表示：（X，Y，Z）。

任务：

 Write a function that takes two vectors (arrays) as input and computes their cross product. 

您的函数应在无效输入（即不同长度的向量）上返回null 。

Instructions

Tests

tests:
  - text: dotProduct必须是一个函数
    testString: 'assert.equal(typeof crossProduct, "function", "dotProduct must be a function");'
  - text: dotProduct（）必须返回null
    testString: 'assert.equal(crossProduct(), null, "dotProduct() must return null");'
  - text: 'crossProduct（[1,2,3]，[4,5,6]）必须返回[-3,6，-3]。'
    testString: 'assert.deepEqual(res12, exp12, "crossProduct([1, 2, 3], [4, 5, 6]) must return [-3, 6, -3].");'

Challenge Seed

function crossProduct() {
    // Good luck!
}

After Test

console.info('after the test');
