type Shift<T> = any

验证

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

type cases = [
  // @ts-expect-error
  Shift<unknown>,
  Expect<Equal<Shift<[]>, []>>,
  Expect<Equal<Shift<[1]>, []>>,
  Expect<Equal<Shift<[3, 2, 1]>, [2, 1]>>,
  Expect<Equal<Shift<['a', 'b', 'c', 'd']>, ['b', 'c', 'd']>>,
]
