Advanced Scala
4 days
Overview
Scala is a type-safe programming language that runs on top of the JVM. Scala is tagged as the “long time replacement for Java”. Scala is both object-oriented and functional, thus allowing developers to easily express themselves using powerful tools without losing performance.
In this 4-day course, we’ll focus on the advanced syntax features that Scala offers.
We’ll also dive into Functional Programming idioms and how to implement them in Scala.
Prerequisites
Good Scala Knowledge.
Audience
Scala developers, Team Leaders.
