Is it possible to create a conditional type based on a literal array type?
Post Body

I'm wondering if it's possible to create a conditional type based on if a value is in an array of literal values:

```js export type UseTablePlugins = "search" | "pagination";

function useTable<Plugins extends UseTablePlugins[]>(plugins: Plugins) { ...

// This is the part I'm stuck on return searchState: Plugins extend "search"[] ? [string, Dispatch] : never; } ```

I know TypeScript goes away on runtime and therefore is unable to find the values of variables, but I'm wondering if I do something like useTable(["search"]) if TypeScript will understand that search is in the type? I hope I'm making sense :).

EDIT: Here's a minimal example for anyone who wants it :)
