I want to develop caht app for mobile platform, but I want to be sure which programing language best for concurrency and Parallel programing like elixir, erlang or golang?

The answers might be a bit biased here :slight_smile: Obviously Elixir.

The BEAM vm is good at this. Between Erlang and Elixir, it’s just a question of syntax.

Maybe you want to consider that the people who did this already quite successfully (WhatsApp) used Erlang? :wink: As @kokolegorille mentioned, whether Erlang or Elixir is a matter of taste. Just if you’re considering a web-frontend you might want to go with Elixir/PhoenixFramework/LiveView…

If you work in an organization who has an existing ecosystem, and every person in the organization is re…

[image] Sebb: Thousands or billions of users? yes sure, like whats app, I guess js and firebase for small team

[image] mpope: Does it need to ‘scale’? If the backend will have a max of 100 to 500 concurrent users at a time, do you need an ecosystem that is highly concurrent? no, I prefer chat app like whats app, it is not small app

[image] Sebb: You can easily build a chat app with a few lines of JS and firebase. Using firebase would be cheating :slight_smile: [image] Sebb: Go has Goroutines - functions that run concurrently - easy, solid and fun. Erlang/Elixir implement the Actor Model. Not that simple but therefo…
