Description
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
