Introduction to Scala

Welcome to Scala! You'll learn what Scala is, who uses it, and why you should use it. You'll explore four common data types: integers, floating-point numbers, logical values, and text, using the Scala interpreter.

Discover two more ways of writing Scala code (writing a script and building an application) and popular tools that make writing these programs easier. Then, learn what functions do and how to use them, and structure your data using the Array and List collections.

Learn about Scala's advanced static type system. After learning how to control your program with if/else, while loops, and the foreach method, you’ll convert imperative-style code to the Scala-preferred functional style.
