Maaan! I just saw the official Video from google “Data Classes - Kotlin Vocabulary “ and was good but I still did not fully get it. I instantly searched “Data Class” in your channel and your video helped me a lot! 💪🏻😃 Would be cool if you can create videos based on Android Dev Channel with the Simplified Coding touch!! Keep up the good work 🙏🏻❤️

A fruit full thanks to you sir for this beautiful tutorial.
But I have a question.
Why kotlin compiler generates componentN methods instead of just using getters?
If you check out decompiled kotlin bytecode you'll notice that componentN methods and getters are exactly the same.

Please answer.
It's my humble request to you sir.

Sir please make a video on OOP. We want to clear the concepts.
