Looks like functional programming is gaining a lot of traction for quite some time now. I just started reading about Elixir and it seems like a promising language that also focuses on developer happiness just like Ruby but with the notion that it is fast, highly-scalable and battle-tested (uses the Erlang VM which powers the majority of telecom networks).
We’re getting more CPU cores than ever and using a functional language like Elixir gives developers the capability to write concurrent applications by thinking about processes.
The creator of Elixir, Jose Valim, was actually a part of the Rails core team and has contributed a lot to the Rails ecosystem.
While it is still a young language, there are already a lot of resources and references available on the web which makes it easy for new developers to dive in and get started.
There’s even a conference about it. It is unusual for an early language to organize one.
The documentation is very well-written and easy to grasp.
Personally, it didn’t take me long enough to decide whether to learn Elixir or not. At first, I was looking at some Go code and it just didn’t resonated with me. Compared to Elixir which has got me hooked immediately.
I guess me being a Ruby developer has influenced my decision to learn this language. The syntax and tooling of Elixir didn’t seem new to me. In fact, it’s like coding in Ruby only with some minor differences.
mixis similar to Ruby’s
An example code.
# Ruby def hello_world puts "hello world" end # Elixir def hello_world do IO.inspect "hello world" end
One thing. If you are used to object-oriented programming, it may take you a little while to get familiar with the functional style of writing. But don’t let that hinder you from learning an interesting language!
Forget all the concepts that you’ve learned about OOP because this is really different. Empty your cup!
If you are also a Ruby developer like me, Immutability may sound very strange to you. Don’t be afraid. Just dive in and sip some Elixir!
Like all other languages, Elixir is not a silver bullet. It is not perfect. It is not always the right decision. It is our responsibility as developers to pick the right language and tools to solve our problems.
