Description
class Base{
age: number;
constructor(age:number){
this.age = age;
}
}
class Concrete extends Base{
constructor(age:number){
super(age);
}
getAge():number{
return this.age;
}
}
export function getAge():number{
let concrete:Concrete = new Concrete(12);
return concrete.getAge();
}When I call getAge(),I expected: 12, in fact I got 0.
Below is the wast text.
