Thanks for asking! I plan to add the TypeScript version to the second edition of the refactoring course. This new edition will be available as a free upgrade to all existing customers. The release date is currently unknown as plenty of work still needs to be done. Besides, the recent events in my home country are hardly helping me focus on this front, unfortunately.
Still, please note that the course is language-agnostic, so you can apply all the gained knowledge to any OOP-focused programming language. Thus if you can read Java, C#, or PHP, you don't have to wait for the second edition.
Please let me know if you have any further questions.
Thank you very much for your response Alexander :). I already purchased the book was just curious about it. Great work btw.
