First version of TypeScript sample repo

[alexcasalboni]

I've converted this PR into its own repo (plus TS-native tests as well).

Also, @Jer1605 any suggestions to make that code more TS-friendly? I've only converted the typing from the JS implementation, but I'm sure that a native TypeScript implementation would look quite different :)

Yes it would, but that's a nice job ! :) You could go further using strict typing (strict mode, noImplicitAny), defining clear interfaces and type aliases, and leveraging generics instead of any to improve safety and readability. Enums and union types are great to enforce constraints, while refining function signatures ensures consistency. Also, making sure module resolution is properly set up and adding ESLint with TS support would help keep the code clean and maintainable. Finally, using Mocha with ts-node as you've already done lets you run tests directly on .ts files. After that, you’ll have a good TypeScript dev setup for a small non complex project (if we need it to be more ingineered, or more scalable, some further config would be needed)! 😃🚀 But getting rid of any is the most important, as it's the nightmare of any TS dev (exceptions can be made in certain specific cases).

Thanks @Jer1605 🙏 I've added ESLint with TS support and removed all any references 👌

Ok, this is ready to merged (no more warnings) 👌
