Scala is an object-oriented language that runs on the Java Virtual Machine. Scala is also a functional language, and combines the features and benefits of OO and functional programming. This course provides a fast-paced introduction to the language for developers with experience in similar languages (e.g. Java, C#, or C++), and then delves deeper into idiomatic uses of Scala in practice.

Duration: 4 days

Who is it for: This course is for programmers who need to develop in Scala
