I have a type as below
type IdAndName = {
id: number;
name: string;
}
Then I need a type that will be union from the values of keys of above type as follow -
type IdOrName = number | string;
Is there any way to achieve this dynamically?

1`type Values
= T[keyof T]; type IdOrNumber = Values – captain-yossarian from Ukraine Jul 15 '21 at 11:33` -
Why don't use `any` type ? – Elikill58 Jul 15 '21 at 11:33

I believe this question is a dublicate, but I can't find the original question – captain-yossarian from Ukraine Jul 15 '21 at 11:33

I believe you meant: `from the values of above type as follow` instead of keys – captain-yossarian from Ukraine Jul 15 '21 at 11:34

Yes, from the values of keys :) Updated the question – Abhinandan Khilari Jul 15 '21 at 11:37

3Does this answer your question? [Is there a \`valueof\` similar to \`keyof\` in TypeScript?](https://stackoverflow.com/questions/49285864/is-there-a-valueof-similar-to-keyof-in-typescript) – KiraLT Jul 15 '21 at 11:42

Tried both `Values
` and `ValueOf – Abhinandan Khilari Jul 15 '21 at 12:48`, but getting errors for both - `Cannot find name 'Values'` and `Cannot find name 'ValueOf'` respectively. Am I missing anything? -
@AbhinandanKhilari you need to write your own `Values` type. Please see my first comment – captain-yossarian from Ukraine Jul 15 '21 at 12:49

Oh, my bad. I missed that. – Abhinandan Khilari Jul 15 '21 at 12:50

@captain-yossarian thanks, that works! By the way, can you help me with a link to official docs for creating such generic types? I am unable to locate that. Would like to go through it to understand. – Abhinandan Khilari Jul 15 '21 at 12:58
