Effective Kotlin requires the use of classes. In this video, we talk about how to instantiate objects using constructors and the init block. We also discuss best practices for object oriented programming (OOP).

Thanks for the excellent video, I learned a lot!
Question? I come from JavaScript and I was wondering does Kotlin have High Order Arrays? Examples would be forEach, map, filter, reduce. Or what about arrow functions? I am spoiled with JavaScript and so far I haven't seen other programming languages with these features. Thank you.!!

Hi Rahul! Nice video!
I was wondering what are your thoughts on the kind of logic that should go into the init{} method.
I'm interested in some cases where instances of ViewModels have their init{} performing some sort of communication with repositories. I have a feeling that init{} shouldn't perform such implicit actions (which may also introduce side effects). Do you have any thoughts on it?
Again, thanks for the content! Have a good day.

Your example is so simple and concise. Straight to the point.

I tried to create the Person class in a separate file. It goes under the resources directory. And I'm not able to import it in my main.kt file. How can I import that kotlin Person.kt file?
