Abstract constructor type in TypeScript

As of TypeScript 4.2, you can use an abstract constructor type:

abstract class Utilities {
    abstract doSomething(): void;
}

type ConstructorFunction = abstract new (...args: any[]) => any;
var UtilityClass: ConstructorFunction = Utilities; // ok!

Was just struggling with a similar problem myself, and this seems to work for me:

type Constructor<T> = Function & { prototype: T }
