How Kotlin fixed Java's unsound arrays: invariance, covariance and contravariance in 3 minutes

[@huttarl]

Thanks for this helpful video. After decades of dabbling in OOP, I'm finally getting serious with Kotlin and learning about variance. Your video explains better than the last one I tried. One helpful tip for non-native English speakers: the stress in "array" is on the *second* syllable. Since the first syllable is unstressed, its vowel has a schwa sound. Many Europeans stress the first syllable, which is wrong, and makes the word difficult to understand.

thanks for the informative videos. with your breadth of knowledge of programming languages how come you never code in scala?

I discovered Scala in 2012 and Kotlin in 2015. I never used Scala to its full potential; Kotlin was simply "good enough" for me, a Java++ or Scala-- if you will. I stopped using Scala in 2017, partly because the Eclipse plugin was just awful. I like Scala's new braceless syntax though 🙃
