Name your title starting with the question no you are trying to answer.

For example: #12 - my one-line solution

type MyPick<T, K extends keyof T> = { [S in K]: T[S] }

In typescrip 4.7.4 this is not work.

type MyPick<T, K extends keyof T> = { [S in K]: T[S] }

interface Todo {
  title: string
  description: string
  completed: boolean
}

/*
type test = {
    title: string;
    completed: boolean;
    invalid: unknown;
}
*/
type test = MyPick<Todo, 'title' | 'completed' | 'invalid'>
