The class assigns a property to an instance member, while the extended class '(Anonymous class)' designates it as an instance member function

Encountering an error:

🔴 Class 'Entity' defines instance member property 'method', but extended class '(Anonymous class)' defines it as instance member function

The code in question is:

export abstract class Entity {

    abstract method: () => void

}

const e = new (class extends Entity {
    method(): void {
        return;
    }

});

An issue similar to this was found on github but the reasoning behind it was unclear: https://github.com/Microsoft/TypeScript/issues/9722

Does anyone have insight into what might be causing this problem?

Answer â„–1

Forget what I said earlier, this response also clarifies my other inquiry:

declare abstract class Model {

    abstract method(): void // <--- it should be a method, not an arrow function

}

const model = new (class extends Model {
    method(): void {
        return;
    }

});
