@bjonnh what are you porting? The good news is ojAlgo is a pure JVM lib, so it should be Java-idiomatic already. I'd like to help on the documentation front and make it more fun to use with okAlgo. My hope one day is to copycat ojAlgo to Kotlin Native, as I've been pretty fond of its API so far with the optimizers.

I've got something you might be interested in along these lines, that i'm getting ready to push soon (whenever someone increases the number of hours in the day). i've started moving towards pure kotlin implementations in koma in order to get more things to run multiplatform. in particular, the options of language-specific libs to delegate to in js are pretty limited, and doing so also means i get kotlin/native support for free
