Kotlin is powerful, elegant, coincise, definitely my favourite programming language by far

[PaulNewport]

I didn't know about partition, or drop. Handy to know!

Digging the tips. Would love more. Thank you.

Typo at 1:14.... "joinToString"

[LouisCognault]

Cool quick tips.
I think it would be better to zoom the UI when you’re not using the entire space like here, so it’s comfortably viewable on mobile or on a tablet.

Nice Tips.
One thing: It would be nice if the results from each tip will be shown a little longer. They disappear a bit too fast :)

It's a great idea! We are waiting for new videos

[jaymartinez]

What plug-in shows the result without a println like that? 🤔 thank you for the great video by the way 😉

[johndoe]

I didn't know that you can use a reference instead of a lambda in that case!
How does it work?

Hot topic... I feel like I know only a small fraction of Kotlin.
