题目

Implement a typeDeepOmit, Like Utility types Omit, A type takes two arguments.

For example:

type obj = {
  person: {
    name: string;
    age: {
      value: number
    }
  }
}

type test1 = DeepOmit<obj, 'person'>    // {}
type test2 = DeepOmit<obj, 'person.name'> // { person: { age: { value: number } } }
type test3 = DeepOmit<obj, 'name'> // { person: { name: string; age: { value: number } } }
type test4 = DeepOmit<obj, 'person.age.value'> // { person: { name: string; age: {} } }

解题思路

待补充

答案

type DeepOmit = any

验证

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

type obj = {
  person: {
    name: string
    age: {
      value: number
    }
  }
}

type cases = [
  Expect<Equal<DeepOmit<obj, 'person'>, {}>>,
  Expect<Equal<DeepOmit<obj, 'person.name'>, { person: { age: { value: number } } }>>,
  Expect<Equal<DeepOmit<obj, 'name'>, obj>>,
  Expect<Equal<DeepOmit<obj, 'person.age.value'>, { person: { name: string, age: {} } }>>,
]
