Haskell is a functional programming language, the structure of which is very different from the popular JavaScript, PHP, Python, or Java – these are powerful hybrid development languages. In addition, some expert programmers believe that developers who understand how functional languages work can better solve the programming tasks in object-oriented languages.
FUNCTIONAL PROGRAMMING
Functional programming has its pros and cons. For example, the imperative approach uses objects, some artificially created instructions, multifunctional – functions, and a set of rules to operate with variables, like strong typization.
Haskell, Erlang, Rust, and Clojure are the bright representatives of the functional programming paradigm. It’s challenging to find a better option to work with DLT or blockchain. On the other hand, such powerful languages as C++ and Java can be the best choice for other tasks, like server operations. Of course, the principles of the first group of languages are not suitable everywhere, but they are practically irreplaceable in their fields.
Functional programming is becoming more and more required due to these factors.
WHY I LOVE HASKELL?
A beneficial feature of Haskel is that it supports an evaluation, which can boost the program, reduce the memory load and make the code more modular. Calculations are done when they are required by the program but not when the programmer specifies them.
Compared to FP in OOP, all the arguments must be calculated in advance, and then a code execution is performed. This process is delayed in programming languages that use attributed computation, and functions are executed only when necessary.
USING HASKELL
Haskell is currently being used in complex fields such as airspace, fintech, education, genetics, etc. Haskell is also used in the banking sector – large banks and financial platforms widely use it to develop their tools. Several pharmaceutical and bioengineering companies use it to analyze medical research and DNA experimental data.
Haskell is often used to create NLP solutions for text processing, parsing, and creating spam filtering systems.

Developers also use Haskell to create testing software to monitor the processes in the systems, written in other programming languages. In addition, it is used to create new custom programming languages.
At the same time, Haskell, used for web development, can be compiled with TypeScript support to run in a browser or on a server as computer code that can freely handle tens of thousands of simultaneous connections.
Conclusion
If you can solve the case via pure logic, you need a simple language to translate the mathematical solution into programming code. If you use object-oriented language, you have to add artificial structures (objects), but with FP languages, like Haskell, you simply put the function into work. So, it’s easy to make abstractions over information and work out methods, which helps you think about the issue without being distracted by unconnected trivia. At the same time, if you wish to solve the problem only by adding ready patterns of code, it’s not how functional programming works.
