Objects and Companions in Scala | Rock the JVM

This is a beginner-level video. If you're learning Scala and its distinguishing feature, this video is for you.

In this video we'll explore Scala objects, which implement the singleton pattern in a single line of code. We look at how Scala classes and objects can work together to form companions, and what's the best practice for structuring your code in between classes and their companion objects in Scala. We also discuss some nuance about the type difference between classes and objects.

Really concise explanation ! The analogy with "static" keyword in java was more than enough to understand what's happening. Nice content !

When you say a class and companion object can access each others private members does that mean the companion object can access the class's private members?
