This is a companion to the book I wrote about datastructure and algorithim in ES6+. It contains the solution to the excercises in the book along with tests.
The code and the tests can be found in ./code/test
The book is published on leanpub.com https://leanpub.com/algorithmenunddatenstrukturenines6
Currently only the German version. I'll translate it into English once I'm done with the German version.
