题目

Implement the type version of Object.fromEntries

For example:

interface Model {
  name: string
  age: number
  locations: string[] | null
}

type ModelEntries = ['name', string] | ['age', number] | ['locations', string[] | null]

type result = ObjectFromEntries<ModelEntries> // expected to be Model

解题思路

待补充

答案

type ObjectFromEntries<T> = any

验证

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

interface Model {
  name: string
  age: number
  locations: string[] | null
}

type ModelEntries = ['name', string] | ['age', number] | ['locations', string[] | null]

type cases = [
  Expect<Equal<ObjectFromEntries<ModelEntries>, Model>>,
]
