purescript VS erlps-stdlib

Some of the problems have been already fixed due to our reports, but some of them haven’t been accepted as they involved some overhead on the performance in the general case. Because of this we have forked the compiler and started adjusting it for our needs ourselves. Our works mainly involve the optimization tweaks and updating the backend to EcmaScript6 (instead of 5). For instance, we have implemented a much more aggressive tail call optimizer, increased strictness of AST traversals and completely rewritten the code generation for pattern match alternatives.

— Elixirscript is a Elixir to Javascript transpiler with similar goals as our project. The main downside of Elixirscript is the lack of OTP support (Erlang’s main framework for building failsafe applications) — it works on a really small subset of the Elixir language and they need to rewrite the Elixir standard library in Javascript for it to work. In contrast we are OTP compatible — we transpiled the real Erlang standard library from OTP and distributed it open-source: https://github.com/erlscripten/erlps-stdlib ( Erlang Solutions ).
