This article features the top 10 rare programming languages that actually pay off.

A programming language is any set of rules that convert strings, or graphical program elements in the case of visual programming languages, to various kinds of machine code output. There are so many programming languages to learn; hundreds of front-end and back-end languages, their frameworks, building applications using them, and so on. Developers and programmers are well aware of a plethora of programming languages. Currently, it is quite important for emerging tech professionals to have a solid understanding of programming languages to pursue a technological career. This article features the top 10 rare programming languages that actually pay off.

Rust: Rust focuses on "type safety, memory safety, concurrency, and performance. Rust seems to have a much brighter future.  Perhaps its newness is why fewer people queuing up to learn it.

IO: Io is a pure object-oriented programming language inspired by Smalltalk, Self, Lua, Lisp, Act1, and NewtonScript. Io has a prototype-based object model similar to the ones in Self and NewtonScript. It is one of the most undervalued programming languages that actually pays well.

Dart: Dart backs the second position in the most underrated programming languages. Unfortunately, Dart was left behind by JavaScript, and the tech giant rebuilt it along the lines of his CoffeeScript. Despite its stronghold within Google, Dart will have to be sold to outside developers.

Nim: Nim is a statically typed language like C/C++, Java, and Go. Nim is very easy to learn but compiles to binaries that execute just as fast as C language. Nim developers wanted to create a language as simple to code as Python, as fast as C, and a language able to create Python extension modules with ease.

Q: Q programming was developed by Kx Systems, a data analytics vendor. It offers multiple approaches to solving a problem, making it versatile. Qhas issues with predictable performance, which could be due to laziness and a higher reliance on garbage collection.

Erlang: Erlang will be well-known to all those who have ever come up with a problem of concurrency. It allows multithreading and uses a virtual machine like Java but unlike the latter, it is meant for embedded systems and very robust servers. Some of its applications are used across telecommunications, banking, e-commerce, computer telephony, and instant messaging sectors.

Groovy: Groovy is another programming language that we have added to the list of unpopular programming languages. Its best features are its simplicity and minimal syntax which can be learned quickly. This programming language is compatible with the Java environment and is used as a scripting language.

Ruby Language: Ruby is an open-source language well known for its simplicity in reading and coding. Ruby language development was to create a functional buffer between human-written code and the underlying machine code. Ruby is mostly useful for developing applications with web architecture.

Scratch: Scratch programming language is a high-level block-based visual programming language and website that aims primarily at children. It enables the users to create projects on the site using a blocky interface. It is free, it is visual, and it is great for games and animation.

Racket: Racket is a multi-paradigm language based on the rudiments of Schem. It is to serve as a platform for language creation, design, and implementation. The Racket guide is one of the clearest and most well-organized documentation available for any programming language today.
