Elixir vs Haskell: What are the differences?
Developers describe Elixir as "Dynamic, functional language designed for building scalable and maintainable applications". Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain. On the other hand, Haskell is detailed as "An advanced purely-functional programming language". .
Elixir and Haskell can be primarily classified as "Languages" tools.
"Concurrency" is the primary reason why developers consider Elixir over the competitors, whereas "Purely-functional programming " was stated as the key factor in picking Haskell.
Elixir is an open source tool with 15.6K GitHub stars and 2.22K GitHub forks. Here's a link to Elixir's open source repository on GitHub.
According to the StackShare community, Elixir has a broader approval, being mentioned in 177 company stacks & 190 developers stacks; compared to Haskell, which is listed in 33 company stacks and 47 developer stacks.

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’s KV store, as well as other backends, including ets, Erlang’s 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).
Why I am using Haskell in my free time?
I have 3 reasons for it. I am looking for:
Improve functional programming skill.
Improve problem-solving skill.
Laziness and mathematical abstractions behind Haskell makes it a wonderful language.
It is Pure functional, it helps me to write better Scala code.
Highly expressive language gives elegant ways to solve coding puzzle.
i've give a try to Ruby, Crystal, Python and GO, and yeah, for web development i use Elixir-Phoenix, because idk why just amazing, my phoenix app is very stable (comparing to api that written in other language), Ruby is slow, Crystal has unstable API, GO, umm yeah, you need too complicated (i use golang for microservice)
Huge boon to productivity when coupled with Phoenix. Moreover, it has made background jobs and all the unseen aspects of a business easily abstracted.
I have been study with videos and tutorials
Backend logic (REST, Auth0, Redis, Postgres, functional graph library (fgl), ...)
