Implement the type version of Object.entries
For example
interface Model {
name: string;
age: number;
locations: string[] | null;
}
type modelEntries = ObjectEntries<Model> // ['name', string] | ['age', number] | ['locations', string[] | null];
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<ObjectEntries<Model>, ModelEntries>>,
Expect<Equal<ObjectEntries<Partial<Model>>, ModelEntries>>,
Expect<Equal<ObjectEntries<{ key?: undefined }>, ['key', undefined]>>,
Expect<Equal<ObjectEntries<{ key: undefined }>, ['key', undefined]>>,
Expect<Equal<ObjectEntries<{ key: string | undefined }>, ['key', string | undefined]>>,
]
