I think developers knowing JS/TS is a highly compelling argument given the fact that most companies are struggling to find any devs at all. I would argue finding Rust/Go/Elixir developers is going to be _a lot_ harder for a lot of companies than finding JS developers. Also then sufficiently proficient frontend Devs have an easy in into backend development which has turned out to be a very good thing at 5 different companies I have worked for in the last 4 years. In addition to that not every backend or service needs much performance. I have written quite a few services that get hit maybe 3 or 4 times a minute at best and Node was great for that. Actually I have yet to work anywhere where performance was limited by the language choice and not by architectural decisions or inconsidered use of databases and data structures. I am not saying this does not exist but it does not mirror my experience with the majority of companies at all. I'd also say that despite npm and dependency hell being a real problem there is a vast ecosystem of packages out there. I know python has that going for it too. But Elixir is much less developed in that regard - simply by being less popular.
