Typescript generic how to make typeof object-to-array?-CodePudding

I have this Function

export const ObjectToArray = <T>(object: T): { key: any; value: any }[] =>
  Object.entries(object).map(o => ({ key: o[0], value: o[1] }));

I want to remove any part of result

I even don't know how to start apporach it.
Any hint please

CodePudding user response：

You could use the following approach:

type Entries<T> = {
  [P in keyof T]: { key: P; value: T[P] };
}[keyof T];

export const objectToArray = <T>(obj: T): Entries<T>[] =>
  Object.entries(obj).map(o => ({ key: o[0] as keyof T, value: o[1] }));

The Entries generic type simply iterates through the keys of T, mapping each key into the record you need, to then indexing those keys to create a union of the records.
Inside the objectToArray function a type assertion is needed because Object.entries does not preserve the informations about the keys of the input object to avoid some unsound situations.
