Why Scalacaster?

Since Fender Stratocaster is a classic guitar, Scalacaster is about classic algorithms and data structures in Scala. Scalacaster includes loads of widely used implementation techniques and approaches, which have been developed by best programmers and enthusiasts of functional programming. Studying purely functional data structures is always fun and challenge for researchers, since data structures in a functional setting are much elegant and smarter than in an imperative setting.

How to use Scalacaster?

Scalacaster is neither a library nor framework. Moreover, Scalacaster`s code is not supposed to be executed at all. Scalacaster's code is not for Scala compiler but for human beings, for enthusiasts and researchers of the Scala programming language and its application in the area of implementation of the purely functional data structures. So, the best way to use Scalacaster is to read through its source code and comments.
