Thanks for the feedback.
We call it new because it is only a year old, and for programming languages its pretty young. It is just now getting mature enough to be able to build real world applications with. Hope it makes sense
I think using a subjective term is meaningless, at least in the context of an introduction. "New" is far too relative, and means something entirely different for one person to the next.
I personally think it makes more sense to provide an objective fact, such as "started in 2022" and let readers determine whether that qualifies as "new" or not.
I wouldn't have mentioned it, and may not have even noticed if it weren't literally the first piece of information presented to me in the repo.
In any case best of luck with the project. It looks very promising and I am excited to see where it goes!
