This course takes advantage of functional programming to make the most of the Scala programming language. In essence, it offers a deep dive into basic functional programming topics, such as algebraic data types, higher-order functions and type classes. In particular, it shows how higher-order functions deprecate for-loops and vars, how they help in error handling and asynchronous programming, and how inheritance and adapters can be superseded by type classes. 

AUDIENCE

• Programmers with some preliminary exposure to the language willing to get a deep dive into Scala from the functional perspective
