The Kotlin track doesn't have learning/tutorial? 100% just challenges?

I was surprised after the Hello World, I just saw an instruction to make acronyms. It’s surprising because JS and Java taught me syntax and keyword so I could create logic, but am I right to assume for Kotlin I will have to look for tutorials online?
Thanks!

That’s correct. Many of the tracks do not have concepts/lessons. The ones that do are the result of countless hours by dedicated volunteers who put in a lot of work to make that happen!

There are easier exercises than Acronym.

When you have worked through a tutorial, perhaps try some of these:

Armstrong Numbers
D&D Character
Darts
Difference of Squares
Eliud's Eggs
Hamming
Leap
Pangram
Protein Translation
Raindrops
Resistor Color
Resistor Color Duo
Reverse string
RNA Transcription
Scrabble Score
Space Age
Two Fer

Acronym is actually quite tricky if it contains HTML test case like in Hashkell track

“HyperText Markup Language → HTML”

With this case added, it requires extra camelCase detection

In Kotlin track, it doesn’t have it so you can just replace some regex patterns with “” and then use split & join.

I can recommend Kotlin Koans and official kotlin lang documentations for learning kotlin. it’s well documented
