Curriculum

1 Introduction to Scala
Learning Objectives:
Get introduced to Scala and learn about the new features of Scala; understand the types

• What is Scala?
• Origin of Scala
• Features of Scala
• Scala Collection Library
• Understanding types in Scala
• Ways to parameterize a type
• Kinds of types
• Using types to express domain constraints

2 Deep Dive into Functions
Learning Objectives:
Look in detail at different flavors of defining a function. Apply the knowledge about types to make our functions polymorphic and of a higher order. Learn about recursion, tail recursion, and trampolining as important aspects of functional programming for the JVM.

• Ways to define a function
• Polymorphic functions
• Higher order functions
• Recursion
• Trampolining
• Object-oriented aspects of functions

Hands-on:
Implement a head-recursive function. Implement a tail-recursive function for factorial calculation. Implement a recursive function for factorial calculation using trampolining.

3 Implicits and Type Classes
Learning Objectives:
Learn about different types of implicits and recap the implicit scope resolution rules. Learn about type classes, the central implementation mechanism that’s utilized in modern functional programming libraries.

• Types of implicits
• Context bounds
• Type classes
• Type classes and recursive resolution
• Type class variance
• Implicit scope resolution rules

Hands-on:
Implement implicit conversions, implicit classes, and implicit parameters.

4 Testing in Scala
Learning Objectives:
Understand the situations in which property-based testing can be especially useful, and look at how the expected properties can be formulated and the test data can be produced.

• Scala testing ecosystem
• Introduction to Behavior Driven Development
• ScalaTest
• Concept of property-based testing
• Properties
• Generators
• Shrinkers
• Properties as laws

Hands-on:

• Define an invariant property for sorting a list.
• Define an idempotent property for sorting a list.
• Define an inductive property for sorting a list.

5 Collections and Functional Programming
Learning Objectives:
Learn about functions and high order functions. Also, learn about the usage of collection library.

• Overview and usage collection library
• Immutability, persistent data structures and structural sharing
• Functions and high-order functions

Hands-on:
Use Immutability, persistent data structures and structural sharing.

6 For Loops and For Expressions
Learning Objectives:
Revisit for loops and for expressions, learn about the differences and compose high order functions.

• For Loops
• For Expressions
• Difference between for loops and for expressions
• Composing high-order functions

Hands-on:
Implement for loops and for expressions.

7 Inheritance and traits
Learning Objectives:
Learn about linearization, scala type system and traits.

• Scala type system
• Mix-in traits
• Linearization

Hands-on:
Mix-in traits in a class to use Linearization process.

8 Pattern Matching
Learning Objectives:
Learn about Pattern matching; exceptions, tuples.

• Usage and benefits
• Catch exceptions
• Deconstruct tuples

Hands-on:
Implement pattern matching by using exceptions and tuples.

9 Exploring Built-In effects
Learning Objectives:
Learn how the mentioned aspects are covered by Scala’s standard library.

• Foundations of encoding runtime aspects with types
• Option
• Either
• Try
• Future

Hands-on:
Explore built-in effects and the effects defined in the standard library, apply option, try, either and then future.
