TL;DR

In this video Tim breaks down the best languages to learn in 2025 by tying each one to specific career goals. He kicks off with JavaScript/TypeScript for web development, then dives into Python for data and automation, C#/.NET for enterprise work, Go for high-performance services, and Java for large-scale backends. He also covers Kotlin/Swift for mobile, PHP for legacy web projects, Rust for systems programming, and good ol’ SQL for database mastery.

Along the way he sprinkles real-world advice on picking the right language based on the job you want, not just what’s “cool.” Plus, he plugs his DevLaunch mentorship program that helps you move from tutorials to actual projects you can show off in interviews.
