Properly type `.constructor` for classes

[hasezoey]

lib Update Request

Configuration Check

My compilation target is es2019 and my lib is esnext.

Missing / Incorrect Definition

.constructor on class instances should return the proper typeof Class type instead of Object.constructor: Function

Sample Code

class Test {}

const instance = new Test();
instance.constructor; // constructor should have the type "typeof Test"
console.log(instance.constructor === Test);

i would need this as a opposite of InstanceType<typeof Class>, for example type TypeofClass<T extends { constructor: new (...args: any[]) => any }> = T extends { constructor: infer S } ? S : never;
