Typescript prevents base classes from being instantiated

class BaseClass{
    constructor() {
        console.log(new.target,new.target == BaseClass);
        // Prevent base classes from being instantiated 
        if (new.target === BaseClass){
            throw new Error(' Base classes can only be inherited , Can't be instantiated ');
        }
    }
}
class SubClass extends BaseClass{
    constructor() {
        super();
    }
}

//let bc = new BaseClass();// Base class instantiation prohibited , Will report a mistake 
let sc = new SubClass();
