Among the huge number of languages, functional languages are gaining more and more fans nowadays and are increasingly being used by companies around the world. You have probably heard about Haskell, Scala, or TypeScript. They are all examples of functional languages.
The reason why small and large companies prefer to adopt FP in areas like fintech, biotech, education, retail, and healthcare is that use of functional languages can significantly improve the productivity and quality of the programmers’ work. Naturally, this depends on the mix of tasks, language and programming skills. Let us learn more about functional programming now so that you could use it in your technological business strategy.
What is functional programming?
Functional programming is the style of writing programs by bringing together different functions. In object-oriented programming, which is more familiar to the majority of people, coders operate objects. Everything is an object, and the relationships between objects are described with functions.
In FP, there are no objects but with functions, it is possible to realize almost any concept of OOP. This principle can be hard to understand, but once you do you notice undeniable benefits. The basic principle of FP is to wrap almost everything in a function, write a lot of small reusable functions, and then just call them one by one. In addition, the structure of these functions must follow certain rules and solve some problems. Basically, instead of describing what you want like in imperative programming, you just give the instructions in code, and the rest is up to the machine to figure out.
The benefits of functional programming have long been recognized by the general public. Successful software development often boils down to maximizing the simplification of existing mechanisms that allow new applications to adapt to the needs of today’s users. And at the same time, we must hurry to be the first ones to present new products to customers. Otherwise, it will be our competitors to do that. Changing requirements are much easier to follow when developed applications can be broken down into a few simple functions that are easy to test.
Where is functional programming used in the real world?
Since functional programming is primarily an approach to writing code, you can use its principles in any language. However, there are languages specially created for the functional approach. More modern functional languages like Haskell, Elm, and Elixir, according to GitHub, are slowly and steadily gaining popularity. In addition, experienced functional programming developers subsequently started working on Single Web Application – SPA environments, and as a result, we have Redux, React, MobX, and other libraries used by millions of people.
If you feel that your coding knowlege does not give you the level of control over the complexity of the business area, try functional programming with Serokell. In areas where there is a lot of computation or data transformation, parallel / asynchronous programming, you can gain significant benefits by diving into functional programming.
