Implement the built-in Pick<T, K> generic without using it.

Constructs a type by picking the set of properties K from T

For example:

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

type TodoPreview = MyPick<Todo, 'title' | 'completed'>

const todo: TodoPreview = {
  title: 'Clean room',
  completed: false,
}
