advanced patterns with Class Inheritance and Static Methods in TypeScript

typescript class inheritance TypeScript

I'm migrating some code and I tried several approaches but none seem to work. I'm working with an scenario with class inheritance in TypeScript, specifically when dealing with static methods. I have a base class `Animal` with a static method `makeSound` and a subclass `Dog` that extends `Animal` and attempts to override this static method. However, when I call `Dog.makeSound()`, it does not behave as expected. Instead of returning the string 'Woof', it seems to be returning 'Undefined'. Here’s a simplified version of my code: ```typescript class Animal { static makeSound() { return 'Generic sound'; } } class Dog extends Animal { static makeSound() { return 'Woof'; } } console.log(Dog.makeSound()); // Expected 'Woof' ``` However, when I run this code, I unexpectedly get 'Generic sound' instead. To troubleshoot, I checked if I had any other static methods in the `Animal` class that might be conflicting, but that doesn't seem to be the case. I also verified that I'm using TypeScript version 4.4.3 and have compiled the code correctly. I’ve tried adding a `super.makeSound()` call in the `Dog` class, but it just returns the base class's sound. What am I missing here? Why isn't my overridden static method in the subclass being called? Is there something specific to TypeScript’s handling of static methods and inheritance that I need to be aware of? Has anyone else encountered this? I'm developing on Ubuntu 22.04 with Typescript. Thanks for taking the time to read this! For context: I'm using Typescript on Debian. Any help would be greatly appreciated! I appreciate any insights!
