Probably should clarify. I think there are better languages in design and safety for backend.
However when it comes to a language you can pick up and crank out code for JS/TS is hard to beat. There’s libraries for everything and if your a full stack dev your probably really familiar with all the ends and outs.
If I have time and I want to make a solidly engineered product Rust is a better option. But often I’m pressed for time and TS can make a solid enough and performant enough product.
