Question

Generator a union that can suport time format type

For example, the function component named 'timePicker' with time params like value、onChange. we need a union type like
'YYYY-MM-DD HH:mm:ss'|'YYYY-MM-DD'|'HH:mm:ss'|'YYYY-MM HH:ss'|... not string, but can be ""

Template

This is the template for challengers to start the coding. Basically, you just need to change the name of your generic/function and leave to implementation any.

type TimeUnion = any

Test Cases

Provide some test cases for your challenge, you can use some utils from @type-challenges/utils for asserting.

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

type Has<T extends string, U extends string> =  U extends T ? true : false

type cases = [
  Expect<Equal<Has<TimeUnion, 'YYYY-MM-DD HH:mm:ss'>, true>>,
  Expect<Equal<Has<TimeUnion, 'YYYY-MM-DD'>, true>>,
  Expect<Equal<Has<TimeUnion, 'HH:mm:ss'>, true>>,
  Expect<Equal<Has<TimeUnion, 'YYYY-DD HH:mm:ss'>, true>>,
  Expect<Equal<Has<TimeUnion, 'YYYY-MM HH:mm:ss'>, true>>,
  Expect<Equal<Has<TimeUnion, 'YYYY HH:mm:ss'>, true>>,
  Expect<Equal<Has<TimeUnion, 'YYYY-MM-DD HH:ss'>, true>>,
