题目

From T, pick a set of properties whose type are not assignable to U.

For Example

type OmitBoolean = OmitByType<{
  name: string
  count: number
  isReadonly: boolean
  isEnable: boolean
}, boolean> // { name: string; count: number }

解题思路

待补充

答案

type OmitByType<T, U> = any

验证

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

interface Model {
  name: string
  count: number
  isReadonly: boolean
  isEnable: boolean
}

type cases = [
  Expect<Equal<OmitByType<Model, boolean>, { name: string, count: number }>>,
  Expect<Equal<OmitByType<Model, string>, { count: number, isReadonly: boolean, isEnable: boolean }>>,
  Expect<Equal<OmitByType<Model, number>, { name: string, isReadonly: boolean, isEnable: boolean }>>,
]
