Which Programming Language Is Right for You?

"Which language should I learn?" is one of the most common questions from people starting out. My answer: start with what you want to build. In my daily work I switch between C#, Java, Kotlin and TypeScript, and for games between Unity and Godot. Each has its place.

By what you want to build

Websites and web apps JavaScript is unavoidable in the browser, and TypeScript makes it far more pleasant for anything bigger than a script. With Node.js you can use it on the server too.

Backend and business applications Java and Kotlin (JVM) or C# (.NET) dominate in companies: mature, fast, with huge ecosystems. Go is popular for cloud tooling and small services, and TypeScript works well for many backends too.

Mobile apps Native means Kotlin for Android and Swift for iOS. If you want one codebase for both, look at Flutter (Dart), React Native (TypeScript) or .NET MAUI (C#).

Games C# with Unity, or with Godot. Godot also has its own easy-to-learn language, GDScript. C++ is the language of Unreal Engine and of engine development itself.

Data, automation and AI Python is the standard here, thanks to its libraries for data analysis and machine learning. It's also great for quick scripts and automation.

Systems programming and performance Rust offers C++-level performance with memory safety. C and C++ remain important for embedded systems and existing codebases.

Tips for beginners

• Pick one and stick with it for a while. The concepts – variables, loops, functions, data structures – carry over to every other language.
• Build something real. A small game, a tool you actually use, a website. You'll learn more than from any tutorial series.
• Your second language is much easier than your first. Don't worry about choosing "wrong".
• Prefer typed languages for larger projects. TypeScript, C#, Kotlin or Java catch many mistakes before your code even runs.
