I don't think you really have to learn a bunch more stuff, but I think it'll be a really nice experience for you to learn a language like Elixir to in the end use Phoenix to set up a web page.

Not because you need it, but because learning Elixir and Erlang with a purpose will give you fresh eyes on development.

I think the above can be said about pretty much any language and their frameworks. Just learn to have learned more and you'll be better for it.
