Subject: [windup-dev] TypeScript static data and inheritance
Message-ID: <364fc58e-0c65-03a6-0cff-50389797be33@redhat.com>

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

|classA {staticfoo 
=[-1];staticgetLastFoo(){returnA.foo[A.foo.length-1];}}classB extends A 
{staticfoo =[1,2,3];// Did this work in TS 1.8?}B.getLastFoo();// <--- 
gives 3|


Ondra

It looks like this.foo still works, only it was made private in the 
super class so it looked like it didn't.
