Ranked in these QuestionsQuestion Ranking
Pros
Pro It is Common Lisp
Lisps are easy languages to learn (once you get past the parens) and Common Lisp is a very practical dialect.
Pro Run almost identically on both the browser and server
Parenscript code can run almost identically on both the browser (as JavaScript) and server (as Common Lisp).
Pro Clear syntax
Uncluttered, yet unambiguous syntax
Pro Excellent community
The Elixir community has proved to be welcoming and very supportive.
Pro Great for concurrency
Leverages the existing Erlang BEAM VM
Pro More familiar syntax
All of the benefits of Erlang; without as steep a learning curve of prolog based syntax. Elixir is heavily inspired by Ruby's syntax which many people love.
Pro Great documentation
Elixir's documentation is very good. It covers everything and always helps solving any problem you may have. It's also always available from the terminal.
Cons
Con The syntax may be hard to learn
Being an implementation of Lisp, Parenscript's syntax may seem cryptic and hard to understand for people not used to it. While Lisp has very little syntax compared to other languages and it's generally considered pretty terse, there's still an initial overhead in learning the language.
