Typescript generic utility type

Question

Is there any utility type in TS to help me get generic type?

I'm looking for something like GenericType

const foo = ['foo']
type MyStringType = GenericType<typeof foo> // equal to type MyStringType = string


let bar : Promise<number>
type MyNumberType = GenericType<typeof bar> // equal to type MyNumberType = number

I am using jest-axe and in let results: axe.AxeResults; I have TS2503: Cannot find namespace 'axe'. error, Also I cannot import AxeResults I want to use GenericType<ReturnType<typeof axe>>

Generic types are usually represented by letters in typescript as in Array<T,U>. Also the most generic type in typescript is any .
