TypeScript 4.0 is recommended in this challenge
Implement a generic Pop<T> that takes an Array T and returns an Array without it's last element.
For example
type arr1 = ['a', 'b', 'c', 'd']
type arr2 = [3, 2, 1]
type re1 = Pop<arr1> // expected to be ['a', 'b', 'c']
type re2 = Pop<arr2> // expected to be [3, 2]
Extra: Similarly, can you implement Shift, Push and Unshift as well?
import type { Equal, Expect } from '@type-challenges/utils'
type cases = [
Expect<Equal<Pop<[3, 2, 1]>, [3, 2]>>,
Expect<Equal<Pop<['a', 'b', 'c', 'd']>, ['a', 'b', 'c']>>,
Expect<Equal<Pop<[]>, []>>,
]
