Thank you for this blog. I like that you tell every time what you are using, what you think and what you do not even know when to use something. This is very useful

Awesome, you're welcome!

That's what I struggled with initially because most of the content out there doesn't explain the usages, as many of them are quite similar.

Just coincidentally, I referred back to this article when I wanted to use one of the scope functions.

I'm glad you find it useful too, and thanks for letting me know.

Thanks for your kind words and feedback. I'm glad you found it useful and informative.

Personally, I do feel that Kotlin makes this scope function unnecessarily complex. That was my first impression, and I still do.

Thanks again for reading and taking the time to share your thoughts with me.
