Data and Control Flow covers the basics of declaring variables and evaluating expressions in the Scala interpreter. The lesson talks about type inference, which spares developers the burden of writing repetitive type signatures all over the code.  The lesson helps viewers to understand how expressions compose cleanly into methods, as well as a new, powerful kind of expression called pattern matching, and it explores how most of the familiar control-flow structures such as “try-catch” blocks and even “for” loops can be treated as composable expressions.  At the end of the lesson, Eclipse is used to implement a simple calculator application.
