What Programming Language to Learn in 2025 and WHY

Most devs end up learning random languages without a clear goal—Tim kicks off by stressing that you need to pick your path first (web, data, enterprise, mobile, systems, etc.). From there he runs through the winners: JavaScript/TypeScript for front-end and full-stack, Python for scripting and data work, C#/.NET for enterprise and game dev, Go for performance-focused backends, Java for big corp ecosystems, Kotlin/Swift for mobile apps, PHP for legacy web, Rust if you want rock-solid systems code, and SQL because every app needs data.

Along the way he sprinkles in pet peeves, real-world pros/cons, and how each language ties back to specific career goals. Plus, there’s a shout-out to his DevLaunch mentorship (hands-on projects, no fluff) and a Kinsta hosting deal for anyone ready to level up.
