Course Overview
Scala is a type-safe programming language that runs on top of the JVM. Scala was 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.
By the end of the 3-day course, the students will know the Scala language, how to use it, applying correct patterns, and will also have extensive hands-on experience which is crucial when learning a new language
