How to get an interface's properties from typescript [duplicate]

Question

I want to get a "postType" Property from an interface defined like this

export interface PostType {
  postType: {
    title?: string;
    content?: string;
  };
}

The purpose I want to take out and use the "postType" Property is as follows

const fn = (post: Post) => {
  ...
}

I used "Pick" but this doesn't work.

export type Post = Pick<PostType, 'postType'>;

The reason I've configured the interface above is that PostType is actually a property that corresponds to another interface.

So I have to follow PostType's interface.

How can I do this?

If I understand correctly you want to do this: PostType["postType"]
