I started with Node and Backbone (then React) and then really got into Rails for a side project and then went to Elixir in 2016. Especially if you've used ImmutableJS, I don't think you'll have a hard time with Elixir. One thing I don't miss about Node is that there are a lot of choices different teams make differently. In Rails or Phoenix (and I'd assume Django), it's a lot more likely that you can jump into an existing project and mostly know where everything is.
