答案

type CompareArrayLength<T extends any[], U extends any[]> = any

验证

import type { Equal, Expect } from '@type-challenges/utils'

type cases = [
  Expect<Equal<CompareArrayLength<[1, 2, 3, 4], [5, 6]>, 1>>,
  Expect<Equal<CompareArrayLength<[1, 2], [3, 4, 5, 6]>, -1>>,
  Expect<Equal<CompareArrayLength<[], []>, 0>>,
  Expect<Equal<CompareArrayLength<[1, 2, 3], [4, 5, 6]>, 0>>,
]
