Five Niche Programming Languages Worth Knowing
Most of us are familiar with popular programming languages like Python, Java, or JavaScript. However, it's sometimes worthwhile to explore so-called "niche" languages that offer unique features and applications.
Why bother learning niche languages?
Learning a niche language is an excellent way to expand your horizons. It allows you to adopt a fresh, entirely new approach to problem-solving, which can lead to more effective programming. A developer who continues to grow is an effective developer.
In the following sections of this article, we'll explore five niche programming languages that deserve attention due to their unique features, applications, and contributions to various programming domains.
APL language
APL (A Programming Language) is a programming language created by Kenneth E. Iverson in the 1960s. Iverson, a Turing Award winner, designed APL to enable programmers to express complex mathematical operations using concise and readable syntax.
Features of APL
APL stands out for its extremely readable syntax, with special characters representing mathematical and logical operations at its core. A unique feature of APL is the array as the fundamental data structure. Here's an example operation in APL:
A ← 2 4 6 8 10
B ← 1 3 5 7 9
C ← A + B
Note the use of the plus sign to sum two arrays. Such an operation in APL can be performed without using loops, showcasing simple, concise, and highly expressive code.
Applications of APL
APL is primarily used in scientific, mathematical, and data analysis fields. With its concise syntax and array operations, APL is ideal for solving problems related to signal processing, statistical analysis, or mathematical modeling.
Elm language
Elm is a functional programming language designed to facilitate the creation of sophisticated user interfaces (UI) through functional programming and strong typing. It is mainly used in web applications.
Features of Elm
Elm is based on the functional programming paradigm, where programs are organized around functions, and variables are immutable. However, what sets Elm apart is its architecture model, known as "
Applications of Elm
Elm finds application mainly in projects related to building user interfaces for web applications. Examples include state management applications, administrative panels, or tools for data visualization.
Raku language
Raku, originally known as Perl 6, is a programming language created as the successor to the popular Perl language. Raku development began in 2000, and the first stable version was released in December 2015. This language was designed to improve various aspects that evolved during the development of Perl 5 while retaining certain characteristic features.
Features of Raku
Raku is characterized by a rich, expressive syntax that allows programmers to write code comfortably and legibly. Its philosophy includes "multilingualism", meaning a programmer can choose from various language constructs to best suit a given task. Raku also supports object-oriented, functional, and imperative programming.
Example Raku code:
class Person {
has $.name;
has Int $.age;
perl
Copy code
method greet {
say "Hello, my name is $.name and I am $.age years old.";
}
}
my $person = Person.new(name => "Alice", age => 30);
$person.greet;
Applications of Raku
Raku has found applications in various fields, including system scripting, web applications, data analysis, and parallel programming. Its versatility and flexibility make it an attractive choice for programmers seeking a tool for different purposes.
Haskell language
Haskell, named after the American mathematician and logician Haskell Curry, is a purely functional programming language. It was created for experimenting with language constructs and introducing innovative ideas from category theory into programming. Haskell is often used in academic environments for teaching functional programming and researching type theory.
Features of Haskell
Haskell stands out with its advanced type system, which eliminates many errors at the compilation stage. Types in Haskell are strong and static, meaning most type-related errors are detected before running the program. Additionally, Haskell uses lazy evaluation, meaning expressions are evaluated only when the result is actually needed, leading to more efficient resource utilization.
Functions in Haskell are treated as first-class values, meaning they can be passed as arguments to other functions, returned as results, and stored in data structures. An example Haskell code:
-- Factorial calculation function
factorial :: Integer -> Integer
factorial 0 = 1
factorial n = n * factorial (n - 1)
Applications of Haskell
Haskell has found applications in various areas, from creating natural language processing tools to implementing compilation systems. Its advantages include type safety, code readability, and the ability to express complex mathematical operations in a concise and declarative manner.

Elixir language
Elixir is a programming language created by José Valim in 2011, inspired by Erlang. Unlike Erlang, which focuses on building scalable and reliable telecommunications systems, Elixir was designed for general use, especially in the fields of concurrent programming, distributed systems, and real-time applications.
Features of Elixir
Elixir utilizes an actor model to handle concurrency. Each actor is an independent entity that can communicate with other actors, send them messages, and react to received messages. Thanks to this model, Elixir enables easy management of concurrency and parallel processing.
Applications of Elixir
Elixir is often used to create distributed systems, especially where low latency and high availability are required. A popular platform based on Elixir is Phoenix, a framework for building web applications that uses the Model-View-Controller (MVC) model and incorporates built-in mechanisms for handling concurrency and real-time communication.
Sample Elixir code:
defmodule MyServer do
use Plug.Router
plug :match
plug :dispatch
get "/" do
send_resp(conn, 200, "Hello, Elixir!")
end
end
The above code is a simple HTTP server in the Elixir language, including code responsible for handling requests.
Summary
In this article, we presented five fascinating niche languages: APL, Elm, Raku, Haskell, and Elixir. Each of these languages offers unique features and applications, serving as inspiration to expand your programming horizons. These languages clearly showcase the richness and diversity of the programming world.
