it’s a great language if you need to develop fast like Python

I think what’s more relevant question here is what about the ecosystem? The language itself can be good, but can you create some category of software in it that is better/easier than alternatives? I suppose it would take a long time for it to have a framework as complete or well documented like Python’s Django or PHP’s Laravel etc.

When blogs or people in forums promote some less used language they often focus on some specific good thing and leave out the inconveniences and the big picture, so these are questions I’d ask before adopting a different programming language.
