I've done this and regretted it - CS transpires to ES3 and specifically null chaining is completely unreadable.

From a backend perspective it's no biggie to instead keep the CS dependency and gradually convert files manually when you have to make changes anyway, or when you have 15 minutes to spare between meetings.

You become fluent enough to not even need tests after a while (yikes!).
