This ranking is the first update of the Functional Programming Languages Sentiment Ranking published in April 2021. 

The sentiment analysis mechanism behind the ranking is based on the most popular achievements related to artificial intelligence – i.e., deep learning networks and embedding. 

We’ve been gathering data for 3 months and have analyzed 160,556 mentions, which have given us insights into 14 functional programming languages (2 more languages than in the previous edition of the ranking). We have aggregated them using the sentiment analysis feature in Brand24.

This report confirms what I've also found in my own experience as an instructor at Rock the JVM: Scala is an expressive and powerful language, and once people get a taste of it, they rarely go back to anything else. Of course, like anything else in tech, there's room for improvement. Because of its power and almost limitless capability, Scala can seem quite daunting to beginners - on this front, it's up to educators like myself to contribute to the community and make the learning process easier and smoother for newcomers.

Functional programming makes code modular and composable, and this can result in an exponential increase in software development productivity. It's interesting to see how functional programming concepts are propagating across more and more programming languages. This research is a key indicator of how to measure the heartbeat, and it tells us that the sentiment is mostly positive. This data can allow language developers to learn from each other's successes, as well as mistakes.

The second edition of our index didn't bring any revolutionary changes. Also hardly any evolutionary. It's too early to identify trends yet, but we're getting there. The new entry of F# at second place is not a surprise. It's well known that both the language and the community are liked and respected. On the other hand Rescript, while far away from the top, is the top FP language on the frontend. I'm quite happy to see it as I would very like to see more adoption of it. Clojure noted the biggest change. Is this a glitch or a trend? We'll keep an eye on that. Scala vs Kotlin is still a close call. So what's next? As I mentioned before, once we have more data, we'll be able to identify trends. I think it would also be interesting to see these changes overlayed with a timeline of events (conferences etc.) for every ecosystem. Also maybe we could start an annual Most Positive Influencer Award? Let me know on Twitter @jczuchnowski.
