Introduction to Scala Course (How To)

The name Scala derives from a combination of the words “scalable” and “language”. Scala is a functional programming language, which runs on top of the Java virtual machine and can use any Java class. Scala is well suited for distributed programming and big data. It is what Apache Spark is built in and can provide better performance when compared to Python and is much less verbose than Java. Whether you’re learning about functional programming or starting a career in big data, Scala is a great place to start.

Functional Programming with Scala

In this stage, you’ll learn about the basics of Scala. We will cover Scala’s origin and its use in some real world applications. In this stage we will learn how to build our first Scala app.

Scala Collections

Data structures are an important aspect of Scala. In Scala, these data structures or collections can range from mutable to immutable. Some of these collections are similar to ones in Java such as arrays and maps or Python such as lists and tuples. In this stage we will learn when to use one collection type versus another and how to implement them.
