Kotlin is one of those things that I avoided learning for so long just because I didn't want to learn another new thing.

And one day I had to work on a project that was 100% kotlin and so i decided to do a 3 hour crash course on Youtube (actually watched it at 3x speed so it was really 1 hour) and once I grasped the basics it really made so much sense and I don't think I'm ever going back to writing Java classes anymore after having seen the light.

Same happened with xpath long back. So long I resisted learning it because CSS selectors did the job but once I reluctantly learned it it changes your whole way of thinking.

I think my fear of learning new things comes from coffeescript, something that actually had a negative impact and I would have better off not learning it which also made me scared of learning new technologies.

Why do you feel like that about Coffeescript?

Would you mind sharing a link to that YouTube crash course? That would be awesome. Thanks.

yeah i'm surprised too, cs wasn't the holy grail but it was a good improvement over es5 at the time.. it really made writing code different

Java developers are rightfully conservative and sceptical of "new things". That said I believe Kotlin really provides a strong value proposition over Java. You also don't sacrifice much, there is less tools ofc but enough to get by, performance is equal for the most part etc.

Also unlike stuff like CS it has a very strong future with Android backing.

Sure it was this one: https://www.youtube.com/watch?v=H_oGi8uuDpA (from history)

I guess I remember incorrectly it was 3 hours long. It is only 1hr few minutes and you can easily watch it at 2x speed.

But overall Youtube is a great resource for learning new things. If you search Kotlin crash course (filter by duration > 20min) you will find ton of such courses and you can easily judge them by number of likes/dislikes.

And make sure to watch it at 3x speed with subs ON initially (video speed controller for chrome). This is truly a great hack when learning tech things via video.

I really don't remember it was a long time ago but from what I recall there was just too much magic happening and things would break a lot of times because it was easy to make mistakes with it.

Come to think of maybe I didn't learn it well enough at that time and blamed it for my silly mistakes. CS did introduce a lot of good things like the fat arrow which was just amazing at that time.

Many years ago, I used to think that Scala was going to be my "next Java".

Now, guess it's not Scala, by Kotlin. Why? - First class citizen for Android development. Yes, most of my works is on Android.

- Not to foreign compared to Java. In general, Java devs should be able to Kotlin in relatively short time. Not sure about Scala, which is influenced by Haskell/ML etc. At least in my circle, not many folks familiar with functional programming.

- Of course now Spring also supports Kotlin :)
