In terms of major companies using Elixir, Discord and Whatsapp are built with it. Whatsapp is slowly chipping away at its Elixir for infra homogeneity reasons with the rest of facebook but discord is still all aboard the Elixir train.

WhatsApp uses mostly erlang if I recall correctly.

Neat, I didn't know about Discord. Whatsapp I thought it was all Erlang, are you sure about Elixir being prevalent there? I wonder if it's only a few teams handling major events at Discord, or if that's truly their default backend service language all their backend teams uses. If so, maybe I should look at their job listings :p

  I think they use Go too.

    They moved from Go to Rust. https://discord.com/blog/why-discord-is-switching-from-go-to-rust https://discord.com/blog/why-discord-is-switching-from-go-to...

  From the discord blog posts it seems that elixir powers the chat system, with rust and python as the other two main languages in their stack. As for whatsapp, they are mainly a erlang shop and yesterday they open sourced a type checker for erlang: https://github.com/WhatsApp/eqwalizer https://github.com/WhatsApp/eqwalizer

    Since Elixir just compiles into BEAM byte code, like Erlang does, can this type checker be used on Elixir code too?
