According to DOU statistics, the majority of Ukrainian developers use two or more programming languages in their work, with more experienced specialists tending to use more languages.
Multilingualism of developers
Prevalence of using several languages
44% of Ukrainian programmers prefer to use two programming language. However, 37% of new developers starting work in 2023 use only one language.
The more experience a specialist has, the more languages he speaks. Only 21% of programmers with more than 10 years of experience use one language, while 43% use three or more languages.
The most popular language combinations
Full Stack and Mobile developers often have to master the largest number of languages. 85% of full stacks already use 2-3 programming languages at the initial stage of their career.
Mobile developers can start working with knowledge of one language - 59% of specialists with less than a year of experience write in only one language. However, in the future there is a need to learn additional languages. Among mobile programmers with more than 9 years of experience, more than half use three or more languages.
Front-end developers, both beginners and experienced ones, predominantly use two programming languages.
Popular combinations among backend developers
Almost a third of backend specialists use only one language in their work, and even among developers with 10 or more years of experience, 24% use only one language is the highest among all specializations.
10% of backenders use exclusively Java, 8% use only C#/.NET, 5% use only Python. They most often choose JavaScript as their second language.
The combination of Python and JavaScript is gaining popularity, used by 12% of newcomers to backend development with less than a year of experience (versus 3% among all backend developers). The demand for the combination of JavaScript and TypeScript is also growing – it is used by 9% of beginners versus 4% among all backend developers.
Frontend Preferences
The majority of frontend developers (76%) write only JavaScript and TypeScript, or one of these languages. About half of front-end developers use both of these languages, 14% use only JavaScript, 8% use only TypeScript. Some experts add PHP to these languages.
Popular languages among full stacks
Full stacks also actively use JavaScript and TypeScript, although not as often as front-end developers. 16% of Full Stack developers write only in these two languages, another 7% write only in JavaScript, 2% write only in TypeScript.
Another common option is a combination of these languages with C#/.NET: 11% of full stacks choose these three languages, 6% - C#/.NET and JavaScript, 5% - C#/.NET and TypeScript . Somewhat less often they are combined with PHP.
Like backenders, full stacks are beginning to increasingly use combinations of JavaScript and TypeScript, as well as Python and JavaScript.
Mobile developer preferences
The most popular combination among mobile development specialists is Kotlin and Java (17% code only in these two languages), another 7% use Kotlin only. 12% use Swift only, 7% use Swift along with C and Objective-C (mainly developers with at least 10 years of experience).
6% of mobile developers prefer C#/.NET only, and 5% prefer Dart only. Kotlin and Dart are growing in popularity in mobile development, especially among beginners.

Four out of ten developers use two programming languages for their work. This is an excellent strategy to expand your capabilities and become a more in-demand specialist. 🚀

But I think it’s better to start with one language. This will allow you to focus and understand its concepts better before taking on a new one. Everyone has their own path, but for beginners, one language may be the best choice. 💡
Dmytro
Interesting numbers about popular programming language combinations. TypeScript and JavaScript are a classic combination for web development. But Python and JavaScript are an intriguing pairing for the backend. 🐍✨
Olena
It doesn't surprise me that full stack and mobile developers are using more languages. They have to cover many aspects of the application, and different languages are better suited for different tasks. 🌐💻
Walter
Hey guys, you're too obsessed with these fancy languages! A true pro must master good old C. All these newfangled things like TypeScript and Python will sooner or later become obsolete, but C will remain forever! 😠🧓

I agree that for beginners one language is a good solution. But as you gain experience, it's important to expand your stack to keep up with the industry. In this sense, DOU statistics are very useful - they show which language combinations are most in demand. 📈💻

I like the growing popularity of TypeScript and JavaScript in backend development. TS brings typing and other features to JS, which improves code quality and performance. A very promising direction! 🌟🔥
Sofiya
It's interesting that even among experienced backend developers, there are many who use only one language. Apparently, in-depth expertise in one area is sometimes valued over versatility. Do you think this is good or bad? 🤔

Great statistics! Personally, I always try to learn new languages and technologies. This way you expand your horizons and remain a sought-after specialist. And sometimes it is possible to find interesting and non-trivial solutions by combining different approaches. 🔥👌
