I don't know if it's because it's directed for beginners, you're probably already aware that at 12:07 you don't need to write the if else statement at all, just put return keyword before the condition written in the if. Less typing :)
This was an awesome explanation. You kept it clear and simple. Plus you showed exactly how the functions were being used so nothing was left to be guessed.
A delegate points to a particular method signatures. And can point to multiple method signatures. A interface is a essentially like a contract that you are essentially agreeing to. For example. A classic example would be Innumerable it's a interface and anything that inherits from it will be forced to also include whatever properties the interface has. Since when you inherit from a interface you are agreeing that you will provide every property method etc from the interface. That being said. You're probably wondering why is this even useful. Imagine you want to loop through a bunch of different objects that are somewhat similar. How can you gurantee to the that function that these similar classes will even have the same property. You would do that with a interface because any class thay inherits from a interface will by contract be forced to implement everything that the interface has or more. And since you know now all the inherited objects that inherit from the particular interface have implemented the fields. You can do something like this void loop(Innumerable en) And anything that inherits Innumerable you can access similar information since they would have implemented similar data. This is the case for collections so lists arrays etc. This is why we are able to use foreach loop on collections because all the collections inherit the interface Innumerable which one of its properties is the getenumberator method. Hope this helped.

Probably the clearest explanation of Lamdas that I have seen.
Great you like it!

Thankyou for such a nice explanation
Very nice explanation of lambdas..
Thank very much buddy
Could you please do some more tutorials on basics of Kotlin in Android Studio
I will update the android 10 course to android 12 and there will be a bunch of kotlin basics coming
@@tutorialsEU Thank You very much 🥰🥰
good

Hey man how can I call function inside lamda expression?
In other words, a delegate is contract for methods as an interface is a classes, isn't it?

@@user-pf9jv1fl2n Thanks it helped a lot
(btw your probably meant IEnumerable not Innumerable)
