kotlin

After one time too many stumbling over a forgotten/unknown function in Kotlin’s “collection” API, I decided to take stock of what’s available.

TLDR - That API is pretty large.

Sometimes it is useful to look at a subject from a slightly different perspective, this provides a sort of mental “binocular vision” and allows to flesh out some details that are less obvious otherwise.

Some languages provide a facility to return an error from a call to method/function, along with the actual result value. This allows (or forces) the programmer to take into account potential runtime errors.

Something similar can be done in Kotlin.

I enjoyed reading the The Fibonacci Problem blog post that shows (among other things) a tail recursive algorithm for the Fibonacci sequence.
