What Programming Language to Learn in 2025 and WHY

Tim kicks off by stressing that most devs pick languages without a clear goal—so before you dive in, figure out whether you’re building web apps, crunching data, writing backend services or targeting mobile. Once you know your aim, you can avoid wasting time on the wrong tech.

Here’s his fast-and-fun lineup:

• JavaScript/TypeScript for web front- and back-ends
• Python for scripting, data science and automation
• C#/.NET for enterprise and Windows apps
• Go for high-performance backends
• Java for legacy systems and Android
• Kotlin/Swift for modern Android/iOS
• PHP for WordPress and simple sites
• Rust for low-level, safe systems
• SQL for any data-driven project

Plus, if you need extra accountability, he plugs DevLaunch—his hands-on mentorship to build real projects and land that job.
