Hi devs,

I am looking for a mechanism to have some static methods operating on data which can be overriden.

U used to do it with an overriden static member, but it seems that TypeScript got stricter and doesn't allow that anymore.

How would you implement that?  Is there some singleton concept in TypeScript?

Thanks, Ondra

class A {
    static foo = [-1];
    static getLastFoo(){ return A.foo[A.foo.length-1]; } 
}

class B extends A {
    static foo = [1,2,3]; // Did this work in TS 1.8?
}

B.getLastFoo(); // <--- gives 3

Ondra
