Course of Introduction to Scala

💸 First lesson available without registration!

Scala is on everyone's lips. It is a concise language, very little verbose, with a lot of ease for functional programming but without forgetting object-oriented programming.

In this course you will learn:

• What pros and cons Scala has as a language and ecosystem
• How to set up your development environment
• Create your first project in Scala from scratch
• Basics of the language. Always assuming you already know how to program, we will focus on specific features like the difference between var, val and def, and some more curiosities
• Control flow. What difference do Scala's "for" loops have compared to the usual ones?
• Higher-order functions, lambda expressions, and currying
• Generics. A brief introduction necessary if you come from a language that does not support this type of abstraction
• Difference between class, case class, and companion objects
• Introduction to ScalaTest to execute our first tests in Scala
• When to choose to model our classes as Enums, sealed trait or sealed abstract class
• How to manage asynchrony through Futures
• Once you finish, you will be ready to take the course on your first HTTP API with Scala and Akka to finally be able to take the refactoring course towards a more functional approach using TypeClasses.

This is not a theoretical course based on slides. We will see all these concepts with code examples little by little 🙂
