So a few days ago I found a programming language called Imba. And I think it is an excellent web programming language. It is very fast, has a clean and easy to read syntax, compatible with any JS library (since it compiles to JS), has inbuilt CSS, can be used to build a full-stack website, and has been in active development for a long time (6 years). It is relatively unknown, so there are not many big projects built with Imba. Two of the big projects that I found so far are Scrimba (an online learning platform) and Iceland's fish auction market.
