Exactly Michael!

Because about TS or JS, it does not matter. In my case, I often use ".ts", but I also use a lot ".js", it all depends of the environment or what I feel right for each occasion. For example, for node projects, in my case is often ".js". But, unless it is just a few dozen lines, I add some type declarations here and there, just to help the IDE make my /** @type Kind */ life easier. ;)
