What is Elixir: A brief history 

Elixir is a functional, dynamically typed language for developing scalable and maintainable applications that are built on top of Erlang's VM and compiled to Erlang bytecode. 

It was created in 2011 by José Valim and has since become one of the most important languages in the Erlang VM ecosystem, focusing particularly on concurrency, reliability, and scalability. It also scales well without sacrificing performance, making it ideal for handling millions of concurrent users in your app or website. 

Features of Elixir that make it relevant in 2022 

  1. Scalability — All Elixir code runs inside lightweight, segregated processes that communicate via messages. 
  1. Concurrency — Elixir may execute multiple processes at the same time, all of which are managed in real-time without causing any negative consequences or slowing down the application. 
  1. Fault Tolerance — Elixir provides supervisors with that define how to restart sections of your system by including built-in safety procedures, which allow the product to continue to function even when anything goes wrong. 
  1. Functional programming It is a coding approach that encourages developers to produce code that is concise, fast, and easy to maintain. 
  1. Erlang Compatibility Elixir runs on the Erlang VM giving developers complete access to Erlang’s ecosystem. 
  1. Elixir comes with a set of development tools. Mix is an example of a tool that makes it simple to set up projects, manage tasks, and run tests, among other things. It also has its own package manager − Hex.

Applications of Elixir Language 

If a single task is difficult to compute and takes significant CPU resources, such as advanced mathematics problems, one should consider using another programming language. 

However, practically any use case that is neither CPU-bound or fundamentally sequential is likely to be a suitable fit for Elixir. Elixir works well for systems with a high volume of traffic, a large number of connections, or connections that are I/O bound. This statement applies to a wide range of modern use cases, including chat backends (such as Facebook Messenger and WhatsApp), web servers, APIs, online applications, and others. 


Usage of Elixir in Live Production 

Different companies across different industries use Elixir to create and grow their businesses in many ways. Some of the companies include Discord, Heroku, Adobe, Motorola Solutions, and many others.

Hiring an Elixir Developer for your team 

While the top programming languages like Java, C, C++, PHP, and JavaScript are default choices for application development, it pays to also consider smaller players as they can offer features that aren’t present in the more prominently used languages. However, a fact to consider before hiring an elixir developer is that there’s a dearth of developers who are proficient in the language; for the developers, there aren’t a lot of learning or growth opportunities. 

We have looked at the Elixir programming language and its features and the applications where it can be used. 

If you are in search of the best Elixir software developer for you, you have come to the right place!
