Why is elixir good for concurrency?

Elixir’s processes are isolated from one another, they do not share any memory and run concurrently. They are very lightweight and the BEAM is capable of running many thousands of them at the same time.

What is concurrency in Elixir?

Concurrency in Elixir (and Erlang) is based upon the Actor Model. Actors are single threaded processes which can send and receive messages amongst themselves. The Erlang VM manages their creation, execution, and their communication.

What is OTP Elixir?

What is OTP? OTP is an awesome set of tools and libraries that Elixir inherits from Erlang, a programming language on whose VM it runs. OTP contains a lot of stuff, such as the Erlang compiler, databases, test framework, profiler, debugging tools.

What is Erlang good for?

It is excellent for: Chat apps. Messaging apps, including some famous examples like WeChat and WhatsApp, use Erlang to handle insane amounts of concurrent users. Erlang has a wonderful messaging platform called ejabberd that can be used to create large-scale chat apps.

What’s the difference between Java and Erlang concurrency?

In fact, we’ve previously looked at them in a previous post on Flavors of Concurrency in Java. Erlang’s take on concurrency is far simpler, since the immutability of data is strongly encouraged by the language itself, meaning Erlang doesn’t allow its threads to access shared data.

What is Erlang used for?

Quoting the language authors: “Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability”. Since its inception it has had a solid understanding of the problems it has intended to solve. Any design trade-offs could have been solved by focusing on a single goal.

What is the difference between Erlang and Elixir?

Erlang and Elixir are completely identical in first two roles – they target the same “thing” (EVM), and they both take a functional approach. It is in role three where Elixir improves on Erlang, and gives us additional tools to organize our code, and hopefully be more efficient in writing production-ready, maintainable code.

What is expressexpressions in Erlang?

Expressions are the building blocks of an Erlang program, used to organize data into the data types (tuples, lists, maps, etc) and perform operations on them like math or by calling other functions. Erlang really respects the immutability of the data, making the variables assignable only once in a scope.
