Kotlin öğrenmeye nereden başlamalı?

For starters, grab the official Kotlin documentation—it’s actually really well-written and beginner-friendly. Start with the basics: syntax differences from Java (if you know it), null safety (`lateinit` vs `?` operators), and coroutines if you plan to do async stuff later. Make sure you set up IntelliJ IDEA or Android Studio right away; both have first-class Kotlin support and live templates that’ll save you typing headaches. Then pick one structured path: I’d recommend starting with the free Kotlin for Beginners courses on JetBrains Academy or the Kotlin Bootcamp for Programmers on Udacity (they’re sequential and project-based). Don’t just watch—actually write the code snippets they provide. After you’ve got a handle on the syntax, shift gears to building tiny CLI tools or simple backend endpoints using Ktor. That forces you to think about real-world trade-offs instead of just running “Hello World” forever. Core topics to prioritize: collections API (map/filter/reduce), sealed classes, data classes, and the standard library functions (takeIf, also, let, etc.). Once you’re comfortable with these, dive into coroutines—start with `runBlocking`, `launch`, and `async/await`, then move to structured concurrency. Build something stupid simple like a file watcher or a basic REST scraper. You’ll hit edge cases fast and that’s where real learning happens.
