What should you learn in 2025? It all depends on your goal: think web apps with JavaScript/TypeScript, data work in Python, big corporate shops with C#/.NET or Java, mobile magic via Kotlin/Swift, or high-performance services in Go and Rust. Even classics like PHP for quick backends and SQL for database mastery have their place—just pick the tool that matches the job you actually want.
And if you’re tired of endless tutorials, Tim’s got DevLaunch—a hands-on mentorship to help you build real projects, stay accountable, and land that dev role without the fluff.
