/**
|
|
Extract all readonly keys from the given type.
|
|
|
|
This is useful when you want to create a new type that contains readonly keys only.
|
|
|
|
@example
|
|
```
|
|
import type {ReadonlyKeysOf} from 'type-fest';
|
|
|
|
interface User {
|
|
name: string;
|
|
surname: string;
|
|
readonly id: number;
|
|
}
|
|
|
|
type UpdateResponse<Entity extends object> = Pick<Entity, ReadonlyKeysOf<Entity>>;
|
|
|
|
const update1: UpdateResponse<User> = {
|
|
id: 123,
|
|
};
|
|
```
