Top 3 Functional Programming Languages

by Simon Hopes Author

Functional programming languages have active communities of experienced professionals. However, so far, these technologies are used by a relatively small number of software companies. This group of languages includes Haskell, Agda, Elixir, Rust, and some more. To learn more about FP, check out the blog of functional developers from Serokell. 

 

Anyway, let us look now at the most promising functional languages that are gradually becoming more and more popular for industrial applications. 

 

FP languages to adopt for your project

 

Agda

Agda is a programming language with dependent typing. It has inductive families, in other words, data types that depend on values, such as the type of vectors of a given length. It also has parameterized modules, mixfix operators, Unicode characters, and an interactive Emacs interface that can help a programmer to write a program. 

 

Agda is a verification assistant. It is an interactive system for writing and verifying evidence. Agda is based on intuitionistic type theory, the foundational method of constructive mathematics. It has a lot in common with other evidence-based assistants based on dependent types such as Coq and Epigram. Learn here how to apply Agda for formal verification. 

 

Elixir

Elixir is a general-purpose language that enables you to make fast, scalable applications that are easy to maintain. It compiles to a bytecode executable on an Erlang virtual machine (BEAM). 

 

At the moment, Elixir is mainly used for building web applications either in Cowboy, which essentially is an HTTP server or in a full-fledged Phoenix web framework. Using the Nerves framework, it also began to penetrate the niche of embedded systems.

 

The Elixir syntax and toolkit is largely borrowed from Ruby. Although the similarity of the syntax is purely external, the Elixir tools will seem familiar to everyone who has already mastered Ruby. 

 

The popularity of Elixir and Phoenix is ​​growing steadily. Together, they make it easy to create complex, time-consuming web APIs and applications that are scalable and easy to maintain. That is why Pinterest, Bleacher Reports, and many other companies have chosen Elixir to create essential infrastructure for their products. 

 

Rust

Rust is a system programming language that combines the efficiency and control of C memory and has the features of functional languages, such as strong static typing and type inference. The main goals of its creators were to increase safety and speed. In many C-like languages, manual memory management leaves the risk of memory errors. Rust has incorporated the best practices of modern C++ versions, such as the RAII idiom or smart pointers, and their use is made mandatory. This systematically provides secure memory access for pure Rust code. At the same time, Rust simplifies programming without losing speed using “zero-cost abstractions.” For example, Rust manages memory during complications and applies static dispatching for generics.
