65 examples that will bring Scala to life for you
These 65 examples will make this cool-new-kid-on-the-block your steady, reliable friend
Let's parse that.
- Scala is cool because its all the rage for big data applications, and because it manages to be more sophisticated and elegant than Java.
- That said, Java is a steady, reliable friend - a language you can depend upon, and in which you can express yourself.
- These 65 examples will help you trust Scala the way you trust Java. Each is self-contained, has its source code attached, and gets across a specific Scala use-case. Each example is simple, but not simplistic.
- The Big Ideas: Before we get to the how, we better understand the why - this course will help clarify why we even need Scala when Java serves us so well
- The Little Details That Matter: Pattern Matching, If Expressions, For Loops & Yield: Java has if-statements, while Scala has if-expressions. Differences like these matter, this course will cover them.
- First Class Functions are perhaps the most dramatically new feature of Scala - the foundation of functional programming support.
- Collections - Lists, Options, the Details of fold/reduce/shift in Scala are yet another bit of the language that differs significantly from other traditional object-oriented languages. We will spend a lot of time on these topics too.
- Classes, Companion Objects, Traits, Self Types and Dependency Injection are Scala's way of providing Object Oriented support. Some of these concepts are similar to Java - those we will skim over. Others are quite different - we will be sure to cover these in detail.
