New abstract constructor type in Typescript 4.2 with support of the constructor arguments

example.ts

type AsFunction<T> = T extends (...args: any) => any ? T : never;
type InferConstructor<T> = T extends { constructor: infer C }
  ? AsFunction<C>
  : () => any;

type Constructor<T> = new (...args: Parameters<InferConstructor<T>>) => T;

type AbstractConstructor<T> = abstract new (
  ...args: Parameters<InferConstructor<T>>
) => T;

interface Test {
  constructor(prop: string);
  method1(): void;
};

type TestType = Constructor<Test>;

const Test: TestType = null;

const test = new Test('smth');
