Tim breaks down how to pick your next language based on your goals—whether you’re shooting for web apps, mobile, backend services or data work. Along the way he drops real-world pros, cons and personal pet peeves about each option, plus a peek at his DevLaunch mentorship program that helps you turn tutorials into job-ready projects.

He then runs through the big hitters—JavaScript/TypeScript, Python, C#/.NET, Go, Java, Kotlin/Swift, PHP, Rust and SQL—highlighting who each language is best for and what roles they’ll open up in 2025.
