Choose a programming language by your goal: Python for AI, data science and automation; JavaScript (and TypeScript) for websites and web apps; Dart or JavaScript for cross-platform mobile apps; C# for Unity games; SQL for working with data; Java or C# for enterprise software. For most beginners, Python or JavaScript is the best first choice.
Start with the goal, not the language
Many beginners spend weeks researching the "best" language. There is no single best; there is the best for what you want to build. And once you know one language well, learning a second is much easier.
Languages by goal
| Goal | Recommended language(s) | Why |
|---|---|---|
| AI, machine learning, data science | Python | Huge ecosystem: pandas, scikit-learn, PyTorch, AI SDKs |
| Websites and web apps | JavaScript, then TypeScript | Runs in every browser; React and Node.js |
| Mobile apps (Android and iOS) | Dart (Flutter) or JavaScript (React Native) | One codebase for both platforms |
| Native Android | Kotlin | Google's preferred Android language |
| Native iOS | Swift | Apple's language for iPhone apps |
| Games | C# (Unity), GDScript (Godot), Lua (Roblox) | Matches the major engines |
| Working with data and databases | SQL | Used by almost every organisation |
| Enterprise and banking systems | Java, C# | Mature, widely used in large companies |
| Systems and performance | C, C++, Rust | Control over memory and speed |
| Automation and scripting | Python, JavaScript | Quick to write, many libraries |
Python
Readable and versatile. The default language for AI, data and automation, and widely used in universities. A strong first language for most people. See our Python tutoring.
JavaScript and TypeScript
JavaScript is unavoidable for web development. TypeScript adds types that catch errors early and is now standard in many professional teams; see why learn TypeScript.
SQL
Not a general-purpose language, but one of the most valuable skills for analysts, developers and business professionals. See SQL for beginners.
What about AI writing code?
AI assistants write code in all popular languages, which makes understanding fundamentals more important: you must be able to read, review and fix what AI produces. Learning one language deeply is still the foundation.
Recommendations by student type
- School student curious about tech: Python.
- Wants to freelance building websites: JavaScript, HTML and CSS; see web development.
- Wants to build apps: Dart with Flutter; see app development.
- Commerce or finance student: SQL and Python for data; see data analytics.
- Loves games: C# with Unity or Lua with Roblox; see game development.
Frequently asked questions
Python or JavaScript first?
Python if you are interested in AI, data or general programming; JavaScript if you mainly want to build websites. Our comparison of Python and Java may also help.
Is C++ a good first language?
It teaches a lot but is harder for beginners. It is common in some university courses and competitive programming.
How many languages should I learn?
Learn one well first. Most professionals use two or three regularly.
