Elm vs Erlang: What are the differences?

What is Elm? A type inferred, functional reactive language that compiles to HTML, CSS, and JavaScript. Writing HTML apps is super easy with elm-lang/html. Not only does it render extremely fast, it also quietly guides you towards well-architected code.

What is Erlang? A programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of Erlang's uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems.

Elm and Erlang can be primarily classified as "Languages" tools.

"Code stays clean" is the top reason why over 37 developers like Elm, while over 49 developers mention "Real time, distributed applications" as the leading cause for choosing Erlang.

Elm and Erlang are both open source tools. Erlang with 7.74K GitHub stars and 2.1K forks on GitHub appears to be more popular than Elm with 5.3K GitHub stars and 424 GitHub forks.

WhatsApp, Heroku, and thoughtbot are some of the popular companies that use Erlang, whereas Elm is used by NoRedInk, Brilliant, and RolePoint. Erlang has a broader approval, being mentioned in 70 company stacks & 47 developers stacks; compared to Elm, which is listed in 27 company stacks and 35 developer stacks.

      Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.
      JavaScript
      JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.

      Postmates built a tool called Bazaar that helps onboard new partners and handles several routine tasks, like nightly emails to merchants alerting them about items that are out of stock.

      Since they ran Bazaar across multiple instances, the team needed to avoid sending multiple emails to their partners by obtaining lock across multiple hosts. To solve their challenge, they created and open sourced ConsulMutEx, and an Elixir module for acquiring and releasing locks with Consul and other backends.

      It works with Consul鈥檚 KV store, as well as other backends, including ets, Erlang鈥檚 in-memory database.

      Another major decision was to adopt Elixir and Phoenix Framework - the DX (Developer eXperience) is pretty similar to what we know from RoR, but this tech is running on the top of rock-solid Erlang platform which is powering planet-scale telecom solutions for 20+ years. So we're getting pretty much the best from both worlds: minimum friction & smart conventions that eliminate the excessive boilerplate AND highly concurrent EVM (Erlang's Virtual Machine) that makes all the scalability problems vanish. The transition was very smooth - none of Ruby developers we had decided to leave because of Elixir. What is more, we kept recruiting Ruby developers w/o any requirement regarding Elixir proficiency & we still were able to educate them internally in almost no time. Obviously Elixir comes with some more tools in the stack: Credo , Hex , AppSignal (required to properly monitor BEAM apps).
