Most Worthwhile Programming Language to Learn in 2023

There's no single "best" programming language, the right one depends on what you want to build, but some languages clearly offer more opportunity and staying power than others right now. Here's an honest look at the strongest options and who each one actually suits.

Python: Versatility and Data Science

Python remains one of the most versatile and widely used languages, and it's usually the easiest to start with thanks to its readable syntax. It dominates data science, machine learning, automation scripting, and backend web development with frameworks like Django and Flask. If you're not sure what you want to specialize in yet, Python is the safest general-purpose starting point.

JavaScript and TypeScript: The Web's Default

JavaScript runs in every browser and, through Node.js, on the server too, which makes it unavoidable for web development. TypeScript adds static typing on top of JavaScript and has become the standard choice for any JavaScript codebase beyond a small size, since it catches a large class of bugs before code ever runs. Learning JavaScript first and TypeScript shortly after is a practical path if web development is your goal.

Rust: Systems Programming and Safety

Rust has been steadily gaining momentum for its emphasis on memory safety without a garbage collector, and for performance close to C and C++. Its compiler catches whole categories of bugs, like use-after-free and data races, at compile time rather than in production. It has a steeper learning curve than Python or JavaScript, but it's increasingly used for systems programming, WebAssembly, and performance-critical backend services.

Go: Simplicity and Backend Services

Go was designed for building reliable backend services and infrastructure tools at scale. It compiles fast, has a small and deliberately simple syntax, and has excellent built-in support for concurrency, which makes it a common choice for cloud infrastructure, APIs, and command-line tools. Companies running large-scale backend systems frequently choose Go for new services.

Kotlin: Modern Android and Beyond

Kotlin is Google's preferred language for Android development and interoperates directly with Java, so it's a natural next step for Android developers coming from Java. It also runs on the JVM for backend work and can target other platforms through Kotlin Multiplatform, giving it more reach than a purely mobile-focused language.

How to Actually Choose

Pick based on what you want to build, not rankings: Python or JavaScript for a broad, beginner-friendly start, TypeScript if you're set on web development, Rust or Go if backend performance and systems work interest you, and Kotlin if Android development is the goal. Learning one language well, and the underlying concepts behind it, transfers far more than trying to learn several languages shallowly at once.
