Programming in Scala 1000-2M25SCA

After completing the course, students should be able to use Scala to create simple but practical applications, such as a web application that accepts user data, saves it, displays it, and allows for its modification and deletion (other possible examples: a desktop application, an Android
application, a video game). They should know Scala syntax, basic concepts of functional programming and their implementation in Scala, as well as be able to plan and configure a Scala project and develop it as a programmer working in a team.
The following topics will be discussed during the classes:
1. Scala syntax: val vs var, immutable vs mutable collections, case class, case object, companion object, sealed trait, enum, apply and unapply, pattern matching.
2. Main concepts of functional programming: functions as data, immutability, laziness (lazy evaluation), type system.
3. Main methods for operations on data collections: filter, map, collect, find, collectFirst, flatMap, fold.
4. Version control system using git as an example. Commands: init, clone, checkout, branch, commit, push. Resolving conflicts using merge and rebase.
5. Futures, async/await, event streams, actor model, Akka/Pekko.
6. Recursion: tail recursion (tailrec), trampolines.
7. Introduction to the debugger and other IntelliJ IDEA features helpful for refactoring, code completion, testing, etc.
8. Monads: Theory, error handling using Option/Either/Try, IO monad in Cats Effect.
9. Implicit parameters and capabilities.
