Precisely, at work we use Python and C++, but I wanted to learn a new language in my own time for fun :)
I also tried to highlight its weaknesses in the Caveats section. The language is young and often has breaking changes which would not be suitable for production at this time, particularly in larger organisations.
However, I think the language shows great promise and will appeal to a lot of people as it matures. I'm certainly enjoying it so far! :)
> I plan to only use this language in my personal projects
I think this is more a blog post about what language the author finds most interesting and exciting, not the language the author is suggesting people use for work.
